Conservation of mechanical energy is defined as

Question 4 options:

Potential energy added to kinetic energy

Law of conservation of energy

The sum of the kinetic and potential energies of an object remains a constant value unless there are forces acting on the object that cause a loss of energy overall, such as friction and air resistance.

Energy of motion

Question 5 (3 points)  

In the EXPLORE section of your lesson 4.08 on Potential energy there were several animations to watch that provided a graphic illustrating how the PE and KE in a system changed as a skateboarder rides a halfpipe or a pendulum moves, why did the bar for the total energy remain constant?

Question 5 options:

all answers given are correct

This is because no energy is being created or destroyed in this system

Because these models do not take into account the impact of friction and air resistance and are helping to solidify the concept of energy conservation and that the total mechanical energy remains constant in that model

Energy is converted from kinetic to potential and potential to kinetic, but the total amount of energy is conserved

Question 6 (3 points)  

Saved

Studying energy involves determining the amount of energy an object has. This energy can be kinetic or potential, or it could be a combination of both. Consider a 2-kg bowling ball sits on top of a building that is 40 meters tall. It falls toward the ground. Think about the amount of kinetic energy the bowling ball has as it falls, select when the ball would have the most kinetic energy from the choices given.

Question 6 options:

as it is halfway through the fall and it has reached a speed of 19.8 meters per second

just before it is to hit the ground and it has reached a speed of 28 meters per second

after it hits the ground and is no longer moving

as it sits on top of a building that is 40 meters tali
