Force and Motion Final Review (24-25)

Front

What is force?

Back

Force is a push or pull on an object that can cause it to move, stop, or change direction.

Front

What is motion?

Back

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

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 is the relationship between force and motion?

Back

An increase in force can lead to an increase in motion, while a decrease in force can slow down or stop motion.

Front

What happens to an object's motion if no force is applied?

Back

If no force is applied, an object at rest will stay at rest, and an object in motion will continue moving at a constant speed in a straight line.

Front

What is the effect of mass on force?

Back

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

Front

What is an example of a situation where force is applied?

Back

Pushing a shopping cart is an example of applying force to move an object.

Front

What is the role of gravity in motion?

Back

Gravity is a force that pulls objects toward each other, affecting their motion, such as causing objects to fall.

Front

How does surface texture affect friction?

Back

Rough surfaces create more friction than smooth surfaces, affecting how easily objects can move over them.

Front

What is the best way to reduce friction?

Back

Using lubricants, like oil, can reduce friction between surfaces.
