Question

2 what would cause a change in a bikes kinetic energy? choose three. pedaling the bike faster applying the bikes brakes while it is moving chaining the bike to a pole storing the bike in an attic pedaling the bike slower

Explanation:

Kinetic energy is the energy of motion, and its formula is $KE=\frac{1}{2}mv^{2}$, where $m$ is mass and $v$ is velocity. Changing the velocity changes kinetic energy. Pedaling faster increases velocity, applying brakes decreases velocity, and pedaling slower decreases velocity. Chaining to a pole and storing in an attic keep the bike stationary with no change in velocity.

Answer:

1. Pedaling the bike faster
2. Applying the bike's brakes while it is moving
3. Pedaling the bike slower
