Newton's 1st & 3rd Laws of Motion

What is Newton's First Law of Motion?

• An object at rest starts moving, and an object in motion changes its direction, unless acted upon by an outside force.

• An object at rest stays at rest, and an object in motion stops immediately.

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

Which law states that an object at rest stays at rest and an object in motion stays in motion unless acted upon by an unbalanced force?

• Newton's Second Law of Motion

• Newton's First Law of Motion

• Newton's Third Law of Motion

What term describes an object's resistance to changes in its motion?

• acceleration

• momentum

• inertia

What is required to change an object's state of motion according to Newton's First Law?

• Inertia

• Gravity

• Outside force

What is Newton's Third Law of Motion?

• Every action has a smaller, opposite reaction.

• Every action has an equal, opposite reaction.

• There is no reaction to an action.

Which law states that every action has an equal and opposite reaction?

• Archimedes' principle

• Einstein's theory of relativity

• Newton's third law of motion

What is the force exerted by an object in response to another object's action force?

• counter force

• resistance force

• reaction force

What is the force exerted by the wall on you if you push it with a force of 10 N, according to Newton's Third Law?

• 0 N

• 10 N

• 5 N

What is the relationship between force and motion?

• Force causes motion in the opposite direction.

• Force is inversely proportional to motion.

• Force has no effect on motion.

Which is a unit of mass?

• Newton

• Kilogram

• Watt
