Which would require a greater force accelerating a 2kg mass?
We can see that the force applied in the first case is greater than the force applied in the second case. Hence, accelerating a 2 kg mass at 5m/s2 requires more force than accelerating a 4 kg mass at 2m/s2.
What force is required to give a mass of 20 kg an acceleration of 30 m s2?
600 newtons
What is the formula for acceleration with force and mass?
According to Newton’s second law of motion, the acceleration of an object equals the net force acting on it divided by its mass, or a=Fm.
What net force is needed to accelerate a 1.25 kg Book 5.00 m/s 2?
So, 6.25 N of force is acting on the book.
How much force is needed to accelerate a 68 kilogram?
The force needed to accelerate a 68 kilogram-skier at a rate of 1.2ms2 is 81.6 Net forces.
How much force is required to produce an acceleration of 2ms 2 in a body of mass 0.8 kg?
Answer. Therefore, Force of 1.6 N is required to accelerate the body.
How is net force calculated?
Formula of Net Force FN is the force acting on a body. When the body is at rest, the net force formula is given by, FNet = Fa + Fg.
Do you add or subtract to find net force?
Net force is determined by adding up all of the individual forces on an object. For example, to determine the net force on an airplane, you would add up the lift, weight, thrust, and drag. If forces are in opposite directions, like lift and weight, then you subtract them.
Is net force always positive?
Forces can be positive or negative. Actually, forces which are aimed to the right are usually called positive forces. And forces which are aimed to the left are usually said to be in a negative direction. Notice that the net force is aimed to the left; so, it is a negative force.
How do you find the net force in Y direction?
Convert the vector (112, 287)N into magnitude/angle form. Use the equation theta = tan–1(y/x) to find the angle of the net force: tan–1 (2.56) = 69 degrees. The direction of the acceleration is the same as the direction of the net force: 69 degrees. to find the magnitude of the net force, giving you 308 N.
How do you find F applied?
The force formula is defined by Newton’s second law of motion: Force exerted by an object equals mass times acceleration of that object: F = m ⨉ a. To use this formula, you need to use SI units: Newtons for force, kilograms for mass, and meters per second squared for acceleration.
What’s a balanced force?
Balanced forces are those that are opposite in direction and equal in size. Balanced forces are considered to be in a state of equilibrium. When forces are balanced there is no change in direction.
What is a balanced force Class 9?
A force where two forces of equal size, act on a body, in opposing directions is known as a Balanced Force. In Balanced Force, a body continues to be in its position i.e. it may be continuously moving with the same speed and in the same direction or it may be still in its position.
What is the acceleration of 10 kg?
2m/s2.
What is the mass of an object that needs a force of 4500 N to accelerate it at a rate of 5 m/s 2?
900 kg
What is the mass of an object that requires a force of 30 N to accelerate at a rate of 5 m/s 2?
6 kg
What is the mass of an object that needs a force of 500 N to accelerate it at a rate of 5 m sec2?
Answer. so, 900 is the mass of that body.
What is the acceleration of a 0.30 kilogram ball that is hit with a force of 25n?
1 Answer. The acceleration of the ball is 83.333ms2 [forward].
What is the rate of acceleration of a 2000 kilogram truck if a force of 4200n is used to make it start moving forward?
Therefore, the acceleration of a 2000 kg truck with a force of 2400 N is 2.1m/s².
What is the mass of an object that needs a force of 4500?
1 Answer. The mass of the object is 900 kg.
What two variables are acceleration dependent?
Newton’s second law of motion pertains to the behavior of objects for which all existing forces are not balanced. The second law states that the acceleration of an object is dependent upon two variables – the net force acting upon the object and the mass of the object.
What are the 3 types of experimental variables?
An experiment usually has three kinds of variables: independent, dependent, and controlled.
Why is force a dependent variable?
The strength of a force is defined by the rate at which it can speed up one kilogram of mass. When two variables are related, one of the variable is free to roam so it is called the independent variable. The other variable depends on the first, so it gets the name dependent. Power is the rate of working.
Can time be an independent variable?
Time is a common independent variable, as it will not be affeced by any dependent environemental inputs. Time can be treated as a controllable constant against which changes in a system can be measured.
Is force a independent variable?
On the other hand, if we consider a situation where the two variables namely force and acceleration of a moving body is taken in to account then acceleration depends upon force and accordingly, acceleration here is the dependent variable and force is the independent variable.
What is the difference between dependent and independent variables?
You can think of independent and dependent variables in terms of cause and effect: an independent variable is the variable you think is the cause, while a dependent variable is the effect. In an experiment, you manipulate the independent variable and measure the outcome in the dependent variable.
How do you know if a variable is independent?
You can tell if two random variables are independent by looking at their individual probabilities. If those probabilities don’t change when the events meet, then those variables are independent. As a simple example, let’s say you have two random variables X and Y. X can equal 0, 1, or 2 and Y can equal 0 or 1.
How do you identify an independent variable?
Answer: An independent variable is exactly what it sounds like. It is a variable that stands alone and isn’t changed by the other variables you are trying to measure. For example, someone’s age might be an independent variable.
What is a dependent variable in an experiment?
The dependent variable is the variable that is being measured or tested in an experiment. 1 For example, in a study looking at how tutoring impacts test scores, the dependent variable would be the participants’ test scores, since that is what is being measured.
What is an example of an experimental variable?
Examples of common experimental variables are: disease. compound. genotype.
What is another name for experimental variable?
Statistics synonyms Depending on the context, a dependent variable is sometimes called a “response variable”, “regressand”, “criterion”, “predicted variable”, “measured variable”, “explained variable”, “experimental variable”, “responding variable”, “outcome variable”, “output variable”, “target” or “label”.
How do you describe a dependent variable?
A dependent variable is what you measure in the experiment and what is affected during the experiment. It is called dependent because it “depends” on the independent variable. In a scientific experiment, you cannot have a dependent variable without an independent variable.
What is the dependent variable in a function?
A dependent variable is a variable that represents a quantity that changes based on other quantities being manipulated in an experiment. In the context of a function, the independent variables are the inputs to the function and the dependent variables are the outputs of the function.
Who are your dependents?
Who are dependents? Dependents are either a qualifying child or a qualifying relative of the taxpayer. The taxpayer’s spouse cannot be claimed as a dependent. Some examples of dependents include a child, stepchild, brother, sister, or parent.
