Forces and Motion/Forces Cause Change Practice

Front

What is a force?

Back

A force is a push or pull that can cause an object to move, stop, or change direction.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, acting in the opposite direction of the movement.

Front

What is gravity?

Back

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

Front

What happens when two forces act in the same direction?

Back

When two forces act in the same direction, they combine to create a larger force.

Front

What happens when two forces act in opposite directions?

Back

When two forces act in opposite directions, they can cancel each other out or create a net force that is the difference between the two.

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

How does mass affect motion?

Back

The greater the mass of an object, the more force is required to change its motion.

Front

What is a push?

Back

A push is a force that moves an object away from the person or thing applying the force.

Front

What is a pull?

Back

A pull is a force that moves an object closer to the person or thing applying the force.

Front

What is the role of a net force?

Back

The net force is the overall force acting on an object, determining its motion.
