Question

Practice Problems. Kinetic and Potential Energy

Answer 1

Answer: 1. Biodist(?) 2. If the one flying at 5mph is going faster(slower) than the other, it has more( less) KE 3. increasing speed increases KE more than increasing mass because KE = 0.5*m*v^2 second 3. Cake tin has greater mass and gravitational PE is proportional to mass. 5. The higher cupcake as greater gravitational PE because it is proportional to height. 6. Electrical, chemical and nuclear PE

Explanation:whatever a biodist is, it probably has greater mass than a mosquito so at the same velocity, has more KE

Unfortunately, “thassing” is unintelligible, but

KE = 0.5*m*v^2

Gravitational PE = m*g*h
