Accepted Answer

Newton's 3rd Law

Answer

Newton's 1st Law

Answer

Newton's second law

Question 13

Newton's first law of motion states that __________.

Accepted Answer

an object will remain at rest or keep moving with a constant velocity unless a force acts on it

Answer

when a force is applied on an object, there is an equal force applied by the object in the opposite direction

Answer

When a force acts on an object, its acceleration is in the same direction as the force

Answer

Acceleration is calculated by dividing the force exerted on an object by the mass of the object
