https://bb.clarkstate.edu/webapps/assessment/tal E] aSearch QUESTION 2 In Unit EM, you saw how contact push/pull interactions can be described using ideas about energy transfers and changes. In this unit, you are developing ideas about how these same interactions can be described in terms of the forces acting on an object. Below is a list of ideas about how the energy and force descri interactions might be related. Which of these are consistent with the evidence you have far?

2.
When a single force acts on a moving object in the same direction as its motion, its KE increases as the force is transferring energy to object.
Its also the energy receiver as its enegry is increased.
If KE is constant, means velocity is also constant and in absence of friction and no other force, there will be no acceleration.
4. While the stick is in contact, it applies a force to the puck that makes its speed increase. As soon is contact is lost, this force disappears so the speed of the puck stops increasing.
