![A truck carrying a box is traveling
60 kilometers per hour. Suddenly, the truck brakes to a stop. Which choice best
explains what will happen to the box? - ProProfs]( "A truck carrying a box is traveling
60 kilometers per hour. Suddenly, the truck brakes to a stop. Which choice best
explains what will happen to the box?")
A truck carrying a box is traveling 60 kilometers per hour. Suddenly, the truck brakes to a stop. Which choice best explains what will happen to the box?- A.
The box will slide off the back because for every action there is an equal and opposite reaction.
- B.
The box will not move because objects at rest tend to stay at rest.
- C.
The box will keep moving forward because objects in motion tend to stay in motion.
- D.
The box will gain speed because, for objects of a given mass, greater force results in a greater acceleration.
- 4.What part of Newton’s first law of motion is demonstrated when a magician pulls the tablecloth out from under a set of dishes?
- A.
An object in motion will tend to be acted upon by an outside force.
- B.
An object in motion tends to come to rest.
- C.
An object in motion will tend to stay in motion.
- D.
An object at rest will tend to stay at rest.
