This is for a quiz, there will be multiple questions! What is true about the distance traveled by the ping-pong ball at the bottom of the ramp?

Question 1 options:

The greater the distance, the more energy the ping-pong ball had

Neither mass nor speed had any impact on the distance traveled

The ping-pong ball did not have any energy as it traveled short or long distances

The greater the distance, the less energy the ping-pong ball had

If a ball is rolling down the hill, what force is acting on this ball?

Question 2 options:

Wind energy

Chemical energy

Gravity

Elasticity

Which statement is true regarding the ping-pong ball at the bottom of the ramp in the experiment, “Rolling Along”?

Question 3 options:

No energy was involved in this experiment.

Only potential energy from the ball coming down the ramp will be given to the ping-pong ball at the bottom of the ramp.

All kinetic energy remains with the ball that is coming down the ramp- none of it transfers to the ping-pong ball at the bottom.

The kinetic energy of the ball coming down the ramp will be given to the ping-pong ball at the bottom of the ramp.

When Is Mechanical Energy Not Conserved?

Question 4 options:

when there is significant friction or air resistance or other force affecting on the object.

when the electricity is turned off

when you are in outer space

when it is cold outside

In which example would the most transfer of energy take place from Mechanical energy to Thermal (heat) energy?

Question 5 options:

When a skydiver opens her parachute

When a metal plate is pressing against a fast spinning piece of steel hard enough to stop it

When a child slides down a waterslide on an innertube

When a feather falls from the sky

When a child slides down a slide (if there is no friction and all of the mechanical energy is conserved) what would happen?

Question 6 options:

Potential energy would turn to Kinetic energy

Kinetic energy would turn in to Potential energy

All energy stays the same

The energy is destroyed

Conservation of Mechanical energy is defined as

Question 7 options:

potential energy added to kinetic 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.

law of conservation of energy

Energy of motion

In the experiment, “Rolling Along”, which ball had the greater mass?

Question 8 options:

Ping-pong ball

The masses are the same

Neither ball had mass

Golf ball

Imagine a skateboarder rolling down a hill. As the rider travels down, the PE is turning into KE. But the rider is still slowing down. What causes this?

Question 9 options:

The rider is feeling the effects of friction

The rider is feeling the effects power transfer

The rider is feeling the effects potential energy

The rider is feeling the effects Kinetic energy
