Front

What is the term for the constant velocity of a falling object when air resistance equals the force of gravity?

Back

Terminal Velocity

Front

What is the net force if the forces acting on an object are 40 N to the right?

Back

40 N right

Front

What is friction?

Back

A force that opposes motion between two surfaces in contact.

Front

What is gravity?

Back

A force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

Front

What is the difference between static friction and kinetic friction?

Back

Static friction acts on objects that are not moving, while kinetic friction acts on objects that are sliding past each other.

Front

What is an example of fluid friction?

Back

A fish swimming in water or a boat moving through water.

Front

What happens to the speed of a falling object as it falls through the air?

Back

It accelerates until it reaches terminal velocity.
