Force, Gravity, & Friction

Front

What is a balanced force?

Back

Forces that have a net force of zero, meaning they do not cause a change in motion.

Front

What are the two types of forces that can make something move?

Back

Pushes and pulls.

Front

What is the force of gravity also known as?

Back

Weight.

Front

What is the net force?

Back

The sum of all forces acting on an object.

Front

What is an example of a helpful friction?

Back

Brakes used on a bike, tires from a car on the road, and tread on the bottom of your shoes.

Front

What is an unbalanced force?

Back

Forces that cause a change in motion, resulting in a net force greater than zero.

Front

What is friction?

Back

A force that opposes the motion of an object.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.

Front

What is kinetic friction?

Back

Friction that occurs when two objects are sliding past each other.

Front

What is static friction?

Back

Friction that prevents an object from starting to move.
