Question

what two variables does kinetic energy depend on?
a velocity and time
b distance and time
c mass and velocity
d mass and volume

Explanation:

The formula for kinetic energy is \( KE = \frac{1}{2}mv^2 \), where \( m \) is mass and \( v \) is velocity (speed in a direction). So kinetic energy depends on mass and velocity. Option a (velocity and time) is incorrect as time isn't in the formula. Option b (distance and time) is incorrect as neither is in the kinetic energy formula. Option d (mass and volume) is incorrect as volume isn't related to kinetic energy's dependence.

Answer:

c. mass and velocity
