Forces and Motion Review

Front

What is a force?

Back

A force is a push or pull that can change the motion of an object.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that cause an object to change its motion because they are not equal in size and direction.

Front

What happens when an unbalanced force acts on an object?

Back

The object's motion will change, which can include starting to move, stopping, or changing 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, often caused by the contact between surfaces.

Front

How does gravity affect objects?

Back

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

Front

What is the difference between speed and velocity?

Back

Speed is how fast an object is moving, while velocity includes both speed and direction.

Front

What is a slope?

Back

A slope is a surface that is at an angle, which can affect how objects move on it.

Front

What is a balanced force?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What is an example of an unbalanced force?

Back

Pushing a stationary car to get it moving is an example of an unbalanced force.
