Back

Newton

Front

The piece of equipment to measure force is called...

Back

Spring Scale

Front

What does friction produce?

Back

heat

Front

__________ is the sum of all forces acting on an object. It is capable of accelerating a mass.

Back

net force

Front

If a toy car and a toy truck are pushed with the same force, why might the car travel faster?

Back

The car had less mass and traveled at a faster speed than the truck.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object.

Front

What factors affect the amount of friction between two surfaces?

Back

The types of surfaces in contact and the force pressing them together.

Front

What is the difference between static and kinetic friction?

Back

Static friction acts on objects that are not moving, while kinetic friction acts on moving objects.

Front

How does increasing the weight of an object affect friction?

Back

Increasing the weight increases the frictional force between the object and the surface.

Front

What is the formula for calculating net force?

Back

Net force = mass x acceleration (F = ma).
