Newton's 1st law of motion is commonly know as:

• The Law of Enertia

• The Low of Inertia

• The Law of Inertia

Which of the following statements is true according to Newton's Laws?

• An object will move faster if the mass is increased.

• An object will stop moving if no force is applied.

• An object will accelerate if a net force is applied.

• An object will move in the opposite direction of the applied force.

Newton's Third Law of Motion states:

• The acceleration of an object is inversely proportional to its mass.

• An object will remain at rest unless acted upon by a net force.

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

• The force of gravity acts on all objects equally.

Which of the following best describes Newton's First Law of Motion?

• An object in motion will eventually stop due to friction.

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

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

• The acceleration of an object is directly proportional to the net force acting on it.

Which of the following scenarios is an example of Newton's Third Law?

• A ball rolling down a hill.

• A person pushing against a wall and the wall pushing back.

• A car accelerating on a highway.

• A satellite orbiting Earth.
