Law of Motion
When a heavy truck and a light truck run into each other, which exerts the most force?
the heavy one
there is no such thing as force
the light one
they are equal
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
Friction
Which best explains why we are able to accelerate forward when we start to run?
As one leg moves backward, it provides an equal and opposite force for the other foot to move forward
The striking foot pushes backward against the ground. The friction with ground provides an equal and opposite force 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?
it stays the same
some of it is transferred to into the energy of the box
None of it is transferred into the energy of the box
it disappears
Which type of energy is due to the motion of particles within an object?
radiant
thermal
nuclear
kinetic
Which best describes the change in energy in this image?

What happens when the ball goes from the highest position to the lowest position
PE and KE increases and decreases together
Impossible to know without knowing the mass of the object
