Which satellite has the greatest gravitational force with earth?
satellite D
What planet has most gravity?
Jupiter
What has the strongest gravitational pull in the universe?
The Sun
What is the name for the force of gravity acting on an object?
weight
What happens to air resistance when an object accelerates?
As an object falls, it picks up speed. The increase in speed leads to an increase in the amount of air resistance. Eventually, the force of air resistance becomes large enough to balances the force of gravity. At this instant in time, the net force is 0 Newton; the object will stop accelerating.
What happens to air resistance when an object accelerates quizlet?
As the object picks up speed, air resistance increases. If the object falls for a long enough time to reach its terminal velocity, the air resistance will equal the object’s weight.
Which object is most affected by air resistance?
Both elephant and feather have the same force of gravity, yet the feather experiences a greater air resistance. Each object experiences the same amount of air resistance, yet the elephant experiences the greatest force of gravity.
Which of the following are two factors that affect how fast an object is moving?
How much matter you have times how fast it is moving equals the momentum of the object. In short, the amount of momentum depends on two factors: mass and speed. Large objects moving quickly have a lot of momentum.
What factors affect the rate an object falls if there is no air resistance?
To answer your question: Air resistance for each object would depend on the surface area of the side facing down to the ground (see aerodynamics), density and shape. If we neglect air resistance, both objects would accelerate equally (as just proven).
Does size affect air resistance?
Air resistance depends on velocity, area, and shape of the object going through the air. Altitude, temperature, and humidity change air density and, consequently, its resistance. The higher the speed and the bigger the area, the higher the resistance.
What affects the rate at which objects fall?
Objects with a greater mass will fall faster (with a greater acceleration?) An objects forward motion will change the rate at which objects fall.
What factors cause an object to fall?
The force of gravity causes objects to fall toward the center of Earth. The acceleration of free-falling objects is therefore called the acceleration due to gravity. The direction of the acceleration due to gravity is downward (towards the center of Earth). In fact, its direction defines what we call vertical.
Why do 2 objects fall at the same time?
If you neglect air resistance, objects falling near Earth’s surface fall with the same approximate acceleration 9.8 meters per second squared (9.8 m/s2, or g) due to Earth’s gravity. So the acceleration is the same for the objects, and consequently their velocity is also increasing at a constant rate.
What factors control how fast an object falls?
The factors affecting the terminal velocity of an object include:
- its mass.
- its surface area.
- the acceleration due to gravity , g.
What controls how fast an object falls?
A: How fast something falls due to gravity is determined by a number known as the “acceleration of gravity”, which is 9.81 m/s^2 at the surface of our Earth. Basically this means that in one second, any object’s downward velocity will increase by 9.81 m/s because of gravity.
