Calculate: Kinetic energy (K) depends on the mass and speed (v) of the object. The equation for kinetic energy is: K = mv2
With Hill 1 set to 75 cm, click Play and allow the car to reach the bottom.

What is the final speed of the car, in meters per second?

What is the kinetic energy of the car, in joules? (Use the mass in kg.)
0.386 J
How does the car’s kinetic energy at the bottom of the hill compare to its potential energy at the top?

Which of the following characteristics of earth's relationship to the sun explains the existence of earth's seasons? choose all that apply. earth has a satellite called the moon, which rotates around earth. earth spins on its axis, completing one rotation each day. earth's axis always points in the same direction relative to the stars. earth's axis is tilted relative to its orbital plane. earth orbits around the sun, completing one orbit each year.
