Newton's Laws & Friction Review

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

Define net force.

Back

The excess amount of force on an object that causes it to accelerate.

Front

What is the normal force?

Back

The force exerted by a surface to support the weight of an object resting on it, acting perpendicular to the surface.

Front

Write the equation for Newton's Second Law of Motion.

Back

Front

If an object is moving at a constant velocity, what can be said about the forces acting on it?

Back

The net force acting on the object is zero.

Front

What is friction?

Back

A force that opposes the motion of an object in contact with a surface.

Front

Differentiate between static friction and kinetic friction.

Back

Static friction prevents motion between two surfaces at rest, while kinetic friction opposes motion between two surfaces in motion.

Front

What is the formula for calculating frictional force?

Back

Front

What happens to the normal force when an object is on an inclined plane?

Back

Front

What is the role of friction in motion?

Back

Friction allows objects to start moving and helps them to stop.
