Back

Static friction is the force that keeps an object at rest and prevents it from moving.

Front

What is sliding friction?

Back

Sliding friction is the force that opposes the motion of two surfaces sliding past each other.

Front

What is rolling friction?

Back

Rolling friction is the force that opposes the motion of an object rolling over a surface.

Front

In which direction does friction act?

Back

Friction acts in the opposite direction of movement.

Front

What is an example of gravity in action?

Back

An example of gravity is when an apple falls from a tree to the ground.

Front

How does gravity affect weight?

Back

Gravity affects weight by pulling objects towards the center of the Earth, making them feel heavier.

Front

What happens to objects in free fall?

Back

Objects in free fall are only affected by gravity and accelerate towards the Earth.

Front

What is the relationship between mass and gravity?

Back

The more mass an object has, the stronger its gravitational pull.
