What are 2 things affect the motion of a falling object?

Air resistance and drag force affect the object’s movement and velocity, relative to its shape.

• The bigger the surface area gets, the higher the air resistance and other factors leading to flying or falling. (
• Air resistance is proportionate to the object’s surface area. (

What are the two main forces that act on falling objects?

Falling objects The weight of the object – this is a force acting downwards, caused by the Earth’s gravitational field acting on the object’s mass . Air resistance – this is a frictional force acting in the opposite direction to the movement of the object.

What force causes objects to fall?

force of gravity
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.

What two factors affect how quickly objects fall in air?

The amount of air resistance an object experiences depends on its speed, its cross-sectional area, its shape and the density of the air. Air densities vary with altitude, temperature and humidity.

Why do two objects fall at the same time?

Consequently, the acceleration is a=Fm=GMR2, which is independent of the mass of the object. Hence any two objects that are subject only to the force of gravity will fall with the same acceleration and hence they will hit the ground at the same time.

What factors will affect a free falling objects motion?

The acceleration of the object equals the gravitational acceleration. The mass, size, and shape of the object are not a factor in describing the motion of the object. So all objects, regardless of size or shape or weight, free fall with the same acceleration.

Why do things fall?

Why do things fall down when you throw them or drop them? The answer is gravity: an invisible force that pulls objects toward each other. Earth’s gravity is what keeps you on the ground and what makes things fall. Objects with more mass have more gravity.

Do 2 objects fall same rate?

So all objects, regardless of size or shape or weight, free fall with the same acceleration. In a vacuum, a beach ball falls at the same rate as an airliner.

What causes objects to fall at the same rate?

This force is caused by air resistance. The less massive the object is, the more the force of air resistance slows the object down as it falls. If two objects were dropped on the moon, where there is no air, they would fall at the same rate no matter how much they differ in mass.

How does air resistance affect the fall of an object?

With air resistance, acceleration throughout a fall gets less than gravity (g) because air resistance affects the movement of the falling object by slowing it down. How much it slows the object down depends on the surface area of the object and its speed.

Why does the force of gravity cause objects to fall?

The bigger the force (the stronger the kick), the bigger change in the football’s acceleration, since its mass doesn’t change. When something falls, it falls because of gravity. Because that object feels a force, it accelerates, which means its velocity gets bigger and bigger as it falls.

What causes an object to fall toward the center of Earth?

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 acceleration due to gravity is constant, which means we can apply the kinematics equations to any falling object where air resistance and friction are negligible.
