Review: Newton's Laws

Front

What is the tendency of an object to resist change in its motion?

Back

Inertia

Front

What type of friction occurs when two objects slide against each other?

Back

Sliding Friction

Front

What is an example of Newton's 3rd Law?

Back

An equal force is being applied by the ball and the soccer player's head on each other.

Front

Define Static Friction.

Back

The friction of stationary objects. You must use more force to move an object experiencing this kind of friction.

Front

According to Newton's Second Law, if the mass increases, what must also increase to move the object?

Back

Force

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What does Newton's Second Law state?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is the formula for calculating force according to Newton's Second Law?

Back

Force = Mass x Acceleration (F = ma)

Front

What is the difference between static friction and kinetic friction?

Back

Static friction acts on stationary objects, while kinetic friction acts on moving objects.

Front

What is an example of fluid friction?

Back

A boat moving through water experiences fluid friction.
