If the mass of the marble was 0.015kg and the roller coaster height is 0.80 m and the value for gravity is 9.8m/s^2. The formula for potential energy is PE=mgh. Calculate the potential energy for the marble.
0.01 J
0.12 J
0.15 J
The kinetic energy of a marble is calculated to be 0.080 J. The mass of the marble is 0.015 kg. Calculate the velocity of the marble using the KE =1/2mv^2
1.1 m/s^2
3.3 m/s^2
5.5 m/s^2
If the mass of the marble was 0.03kg and the velocity is of the marble is 0.20 m/s, calculate the kinetic energy of the marble. KE=1/2mv^2
0.0001J
0.0003 J
0.0006 J
Which of the following has the greatest kinetic energy. The equation for kinetic energy is KE = 1/2mv^2

A 220 kg bear running 18 m/s
A 0.5 kg cannon ball traveling 340 m/s
A 160,000 kg airplane parked at the airport
Which object has the greatest potential energy? The equation for potential energy is PE = mgh. The value for "g" is 9.8 m/s^2.
