Second Law of Acceleration

A sports car speeds up much faster than a tow truck when a traffic light turns from red to green. Which law is this?

• Newton's 1st Law - Law of Inertia

• Newton's 2nd Law - Law of Acceleration

• Newton's 3rd Law - Law of Force Pairs (Action, Reaction)

The greater the mass of an object being moved, the greater amount of force needed to move the object.

• Newton's 1st Law - Law of Inertia

• Newton's 2nd Law - Law of Acceleration

• Newton's 3rd Law - Law of Force Pairs (Action, Reaction)

Which example best explains Newton's Second Law of Motion?

• When a glass slid across a table, it spilled water when it stopped suddenly.

• An engine used less work to move a lighter car than when it moved a heavier car.

• When you sit on a chair, your body exerts a downward force on the surface of the chair, while the chair exerts an equal and upward force on your body.

It takes more force to accelerate the iron man on the left than the iron man on the right because the iron man on the left has more mass. This best describes

• Newton's first law, the law of inertia

• Newton's second law, the law of acceleration

• Newton's third law, the law of action reaction 

• The law of universal gravitation

what happens to the acceleration of an object when the mass is halved? (force remains the same)

• acceleration doubles

• acceleration is also halves

• acceleration increases 4 times

• acceleration becomes zero
