Forces and Motion Review

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 a force?

Back

A 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 speed?

Back

Speed is the distance traveled by an object divided by the time taken to travel that distance.

Front

How do you calculate speed?

Back

Speed = Distance ÷ Time.

Front

What is gravity?

Back

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

Front

What happens to an object in motion if no forces act on it?

Back

An object in motion will continue to move at a constant speed in a straight line if no forces act on it.

Front

What is the relationship between force and motion?

Back

A force can cause an object to start moving, stop moving, or change its direction.

Front

What is the effect of increasing force on an object's motion?

Back

Increasing the force applied to an object will increase its acceleration and speed.

Front

What is the difference between static and kinetic friction?

Back

Static friction prevents an object from starting to move, while kinetic friction acts on an object that is already in motion.
