D: a rock sitting on top of a hill
1 - Xavier pushing Brad down the snowy hill on a sled
2 - A wave crashing on the shore
3 - Energy transfers from Kiara’s fingers to the piano keys
100% Just took the qc
@moist is 100% right
"moist' is correct as of 3/1/2022!
The wave is moving (kinetic).
here are the answer for Which example demonstrates kinetic energy?(1 point) b.a.a
The others have the "potential" to move :)
thx damste1 i got 3/3
moist 100% correct thank you @moist
The correct example that demonstrates kinetic energy is choice A: a wave crashing on the shore.
To understand why this is the case, we first need to understand what kinetic energy is. Kinetic energy is the energy possessed by an object due to its motion. It depends on both the object's mass and its velocity.
In the given options, only a wave crashing on the shore involves motion. When a wave crashes onto the shore, it travels and moves as the water particles in the wave move towards the shore. This motion demonstrates kinetic energy because the water particles possess both mass and velocity as they move.
On the other hand, the other options (B, C, and D) do not involve motion. A stretched rubber band (choice B) has potential energy due to the stored elastic potential energy, but not kinetic energy as it is not in motion. Similarly, a car parked in the parking lot (choice C) is stationary and does not possess kinetic energy. Lastly, a rock sitting on top of a hill (choice D) is also stationary and does not have any motion, so it does not exhibit kinetic energy.
Therefore, the correct example demonstrating kinetic energy is A: a wave crashing on the shore.
