Review on Newton's Laws of Motion and FBD

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 with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

Define net force.

Back

The overall force acting on an object when all the individual forces acting on it are combined.

Front

What is inertia?

Back

The tendency of an object to resist a change in its movement.

Front

What does it mean when the net force is 0 N?

Back

The object is in equilibrium, meaning it is either at rest or moving at a constant velocity.

Front

What is friction?

Back

A force that opposes the motion of an object when it is in contact with another surface.

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it will resist changes in its motion more.

Front

What is the direction of the force of friction when an object is moving?

Back

The force of friction always acts in the opposite direction to the motion of the object.

Front

What is the formula for calculating net force?

Back

Net Force = Total Forces acting in one direction - Total Forces acting in the opposite direction.

Front

What is Newton's Second Law of Motion?

Back

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

Front

What is Newton's Third Law of Motion?

Back

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