Forces and Motion

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it comes into contact with another surface.

Front

What happens to an object when a force is applied to it?

Back

When a force is applied to an object, it can cause the object to start moving, stop moving, or change direction.

Front

What is mass?

Back

Mass is the amount of matter in an object, which affects how much force is needed to move it.

Front

What is motion?

Back

Motion is the change in position of an object over time.

Front

What is gravity?

Back

Gravity is a force that pulls objects toward each other, such as the pull of the Earth on objects.

Front

What is a push force?

Back

A push force is a force that moves an object away from the source of the force.

Front

What is a pull force?

Back

A pull force is a force that moves an object toward the source of the force.

Front

How does surface type affect friction?

Back

Different surfaces create different amounts of friction; rough surfaces create more friction than smooth surfaces.

Front

What is the relationship between mass and distance traveled?

Back

An object with less mass will generally travel a longer distance when pushed with the same force compared to a heavier object.

Front

What happens to a ball when it is thrown?

Back

When a ball is thrown, it experiences a push force from the thrower and a pull force from gravity.
