What is at the top of the cliff?
200
Which has more elastic potential energy, a stretched out slinky, or a slinky that is compressed? How do you know?
What is a slinky that is compressed, because that slinky has a the greater potential to be stretched out?
200
Energy that is stored to be transformed at a later time
What is potential energy?
200
If there is no friction or air resistance, the mechanical energy of a system changes only if the system does not work on something else or energy is added from outside the system
What is the conservation of mechanical energy?
300
What happens to the kinetic energy of a bouncy ball RIGHT after it bounces, as it is heading upward in its' path?
What is the kinetic energy decreases?
300
What happens to gravitational potential energy as a ball bounces upward?
What is gravitational potential energy increases?
300
Which has greater elastic potential energy, a rubber band that is not stretched, or a rubber band that is stretched? How do you know?
What is a rubber band that is not stretched, as it has the greater potential to stretch out.
300
A way to increase (or decrease) an object's energy by using a force to change the object's motion or position.
What is work?
300
Squeezed or pressed together
What is compressed?
400
What happens to the kinetic energy of a bouncy ball as it is falling downwards in its' path?
What is kinetic energy increases?
400
What happens to gravitational potential energy as a ball falls downward?
What is gravitational potential energy decreases?
400
Which has greater elastic potential energy, a bouncy ball, or a baseball? How do you know?
What is a bouncy ball, it has a greater chance to be deformed.
400
What is a push or pull on an object?
What is a force?
400
The force of attraction between any two masses. Near Earth's surface, the force that attracts objects towards the Earth
What is gravity?
500
Which has a greater effect on kinetic energy, mass or speed? Use evidence to back up your claim.
What is speed? Evidence: When the Cart in the Cart/Clay video was pushed at a greater speed, but with less mass, the cart made a greater smoosh than the cart with greater mass, but less speed.
500
Justin Bieber stands at the top of a 1000 foot cliff. Harry Styles stands at the top of a 14,000 foot mountain. Who has greater gravitational potential energy? How do you know?
Who is Harry Styles? He is higher above the ground so he has greater gravitational potential energy.
