Front

What is motion?

Back

The change in position of an object over time.

Front

What is friction?

Back

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

Front

How does mass affect motion?

Back

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

Front

What is acceleration?

Back

The rate at which an object changes its velocity.

Front

What is gravity?

Back

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

Front

What happens when you apply the same force to two objects of different masses?

Back

The object with less mass will accelerate more quickly than the object with more mass.

Front

What is a catapult?

Back

A device that uses force to launch an object, often by bending a lever.

Front

Why is it important to conduct multiple trials in an experiment?

Back

To ensure accuracy and reliability of the results.

Front

What is the relationship between force and motion?

Back

Force causes motion; without force, an object at rest will stay at rest.
