What is the direction of acceleration due to gravity explain with an example?
The acceleration due to gravity is ALWAYS negative. Any object affected only by gravity (a projectile or an object in free fall) has an acceleration of -9.81 m/s2, regardless of the direction. The acceleration is negative when going up because the speed is decreasing.
What is another way to say the force due to gravity ‘?

What was gravity called?
gravitation
Is weight the force of gravity?
Weight W is the force of gravity F g F_g FgF, start subscript, g, end subscript exerted on an object. Mass m is a measure of the inertia of the object (i.e. how much it resists changes in velocity).
Who conceptualized the force of gravity?
Sir Isaac Newton
What is difference between weight and gravity?
The difference is that weight is a consequence of the Force of gravity. Weight is a quantity that you measure for a particular object, while gravity is a measure of how curved is the spacetime where that object is living.
What should my weight be for my height and age?
Measure your waist-to-height ratio To calculate the WtHR, a person should divide their waist size by their height. If the answer is 0.5 or less, the chances are that they have a healthy weight. A woman who is 5 feet and 4 inches tall (163 cm), should have a waist measurement below 32 inches (81 cm).
What is the similarity between gravity and weight?
At the MSL on Earth where gravitational acceleration is g = 9.81 m/s2, the same object will have weight of W = m × g = 2.0 × 9.81 = 19.62 N. If the same object is taken to the centre of the Earth, weight will be zero as gravitational acceleration at the Earth’s center is zero.
What is the similarity and difference between mass and weight?
W = m ∗ g W = m * g W=m∗gComparing Mass and Weight
| Mass is a property of matter. The mass of an object is the same everywhere. | Weight depends on the effect of gravity. Weight increases or decreases with higher or lower gravity. |
|---|---|
| Mass may be measured using an ordinary balance. | Weight is measured using a spring balance. |
What does weight and mass have in common?
In common usage, the mass of an object is often referred to as its weight, though these are in fact different concepts and quantities. In scientific contexts, mass is the amount of “matter” in an object (though “matter” may be difficult to define), whereas weight is the force exerted on an object by gravity.
Does force depend on mass?
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. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object.
Is force and mass directly proportional?
Newton’s second law of motion (also known as the force law ) states that… net force is directly proportional to mass when acceleration is constant. …
