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
