An object at rest will remain at rest unless acted on by an unbalanced force.

• First Newton's law of motion

• Second Newton's law of motion

• Third Newton's law of motion

• Fourth Newton's law of motion

It is also known as the law of inertia.

• First Newton's law of motion

• Second Newton's law of motion

• Third Newton's law of motion

• Fourth Newton's law of motion

What best defines the term inertia?

• The quantity of motion of an object

• Force x time

• An objects resistance to motion

• The change in velocity over time

According to Newton's second law of motion..

• F = m+a

• F= ma

• F = mv

• F= m/a

According to Newton's second law of motion, if the same force is applied to two objects with different masses, the object with the larger mass will have...

• NO CLUE

• THE SAME acceleration.

• A FASTER acceleration.

• A SLOWER acceleration.

Which one best describes Newton's third law of motion?

• The greater the mass of the object being accelerated, the greater the amount of force needed (to accelerate the object).

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

• An object in motion will move at constant speed and in the same direction unless acted upon by an unbalanced force.

• Mmmh not sure

This is the quantity of motion of a moving object, i.e. the product of mass and velocity.

• Impulse

• Acceleration

• Momentum

• Distance
