When a heavy truck and a light truck run into each other, which exerts the most force?

there is no such thing as force

What is Newton's Second Law?

F= ma (Force=mass x acceleration)

an object at rest stays at rest, and object in motion stays in motion

every action has an equal and opposite reaction

Which best explains why we are able to accelerate forward when we start to run?

The striking foot pushes backward against the ground. The friction with ground provides an equal and opposite force forward.

As one leg moves backward, it provides an equal and opposite force for the other foot to move forward

No acceleration takes place. Runners are always at a fixed velocity.

The runner's upper body quickly leans forward, causing the entire body to begin accelerating forward.

What happens to energy as you move a heavy desk across a room?

some of it is transferred to into the energy of the box

None of it is transferred into the energy of the box

Which best describes the change in energy in this image?

Some of the kinetic energy becomes potential energy and then all of the potential energy becomes kinetic energy.

Some of the kinetic energy becomes potential energy and then some potential energy becomes kinetic energy

How is energy transformed with is object in this image?

electrical to radiant to thermal

electrical to thermal to radiant

thermal to electrical to radiant

radiant to electrical to thermal

Which is an example of friction?

brake pads on a bike squeezing on the wheel rim

hammer hitting a nail into wood

electrons flowing through wires

What happens when the ball goes from the highest position to the lowest position

the PE decreases while KE increases

PE and KE increases and decreases together

Impossible to know without knowing the mass of the object
