To solve this worksheet, we need to determine whether each scenario represents
potential energy (P) or
kinetic energy (K). Here's a brief explanation of the two types of energy:
-
Potential Energy (P): This is stored energy due to an object's position or state. It has the potential to do work but is not actively doing so.
-
Kinetic Energy (K): This is the energy of motion. An object that is moving possesses kinetic energy.
Now, let's analyze each scenario:
1.
An egg sitting on the kitchen counter, about to roll onto the floor.
- The egg is stationary but has the potential to roll due to gravity.
-
Answer: P
2.
A baseball in the air, thrown from the catcher back to the pitcher.
- The baseball is in motion.
-
Answer: K
3.
A roller coaster at the top of the hill about to go down the big hill.
- The roller coaster is stationary but has the potential to move due to its height.
-
Answer: P
4.

- The deer is in motion.
-
Answer: K
10.
A kangaroo in mid-jump about to come back down to the ground.
- The kangaroo is in motion but also has potential energy due to its height.
-
Answer: K (Primarily kinetic, but also some potential)
11.
A basketball sitting on the edge of the rim about to fall in the hoop.
- The basketball is stationary but has the potential to fall.
-
Answer: P

14.
A boat speeding across the river.
- The boat is in motion.
-
Answer: K
15.
A soccer ball reaching the highest point about to fall back down.
- The soccer ball is momentarily stationary at the peak but has potential energy due to its height.
-
Answer: P
16.
A bowling ball rolling down the lane.
- The bowling ball is in motion.
-
Answer: K
17.
