Kinetic and Potential energy in each of the following.....
a) an athlete leaving the ground for a high jump
b) a pop fly on its way back down
c) an engine as the driver puts the hammer down
d) a cheerleader cartwheeling across the gym floor

Yes to all 4
yes to all
a) knee
b)ball
c) idk
d) elbow and knees
i think kinetic energy is not stored energy energy thats out in the open?....idk?? i think potental energy is stored energy??
yes
yes
yes
yes
Kinetic: A, B, D
Potential: All four.
a) knee
b) ball
c) idk
d) elbow and knees
a= potential is leaving and kinetic is going up
b= the kinetic energy is lowering and so is the potential
c= the kinetic goes way up the potential is transfering into kinetic.
d= the kinetic energy is fairly high the potential is lowering
A)potential in the knees and kinetic wen he leaves the ground.
B)potential wen it hits the ground and kinetic wen it got hit and is flying.
C)potential in the accelerator before he hits the gas kinetic wen he hits the gas.
D)potential in her arms kinetic wen she lands after the cartwheel.
Potential: athlete feet on the ground, pop fly when it stops,hammer stopping, and cheerleader stoping.
Kinetic:doing the high jump, when the pop fly is falling, the hammer being put down, and cheerleader doing the cartwheel.
In his lags before he jumps
When he lands
In his arm being ready to strike the hammer on the engine
Threw her hole body as she is spinning or at least in her arms and legs
a)potential-before they leave the ground. kinetic-when they jump.
b)potential-before its hit. kinetic-when the ball is in the air.
c)potential-before you press the gas. kinetic-after he pressed the gas.
d)potential-before she starts her first cartwheel. kinetic- when shes doing them.
a)before they leave the ground is potential and when they leave the ground is kintetic
b)potential:when ball is hit
kinetic:when the ball is in the air
c)potential:before he presses the gas
kinetic: when the gas pedal is pressed
d)potential:before the girl starts to bend
kinetic: when shes wheeling across the room.
a)k-when you first push off the ground
p-knees
b)k-when its thrown
p-none
c)k-idk
p-idk
d)k-running before the kartwheel
p-arms and legs
A) potential is in his knees and kinetic is when he is in the ground.
B) when you pull back to throw the ball and when its in the air.
c) when the engine starts and when the driver puts the hammer down.
d) when the cheerleader starts to run and when the cheerleader starts the cartwheel.
kinetic is wen the junper is just leveing the ground and the potential energ is wen hes in mid air
wen the pop leaves the hand and wen its in mid air.
1 potential in knees/kinetic releasing the knees
2ball
3 the bets
4hand knees
A)when you are soaring over (K)
(P)abnout ready to push off
(B)(K)when its thrown (p)on the way back down it doesnt have any
(C)idk
(d) running before she does the cartwheel (K)
p-????arms and legs (force>>>)
a.in his legs
b. there is no kinetic but there is gravity
c.in the motor and gravity
d.in arms and legs and gravity
A)K-when you are falling after going over the bar
P-storing it when you are about ready to jump
B)K-When you are throwing it and when it its coming back down
P-it has no potential energy on the way back down
C)ummm idk
D)K- when she is going around for the second time cause your using your momentum to get over
P-ummm....idk
a) kinetic- legs pushing off ground
potential- in legs
b)kinetic- ball hitting ground
potential- ball in air falling
c) kinetic- car speeding up
potential- pistons moving in engine
d) kinetic- pushing away from floor
potential- Hands and legs
A. In his legs and In his legs.
B. No Kinetic energy but there is potential energy when the ball is going into the glove (Gravity).
C. The engine and there is gravity.
D. The Cheerleader and the gravity pushing her down while she does her cartwheels.
