If the marble had a mass of 0.3kg and the hill was 2.3 m tall, how much potential energy did it have at the top of the ramp?
2.3
.23
6.9
5.2
What is the correct unit for energy?
meters (m)
kilogram meters per second (kg m/s)

What kind of energy does a marble rolling at the bottom of the hill have?
gravitational potential
chemical potential
kinetic
thermal
What is the equation for kinetic energy?
mv
1/2 mv^2
mgh
Ft
If the 0.3 kg marble was moving at 6 m/s at the bottom of the ramp, how much kinetic energy did the marble have?
5.4 J
1.8 J
3 J
6 J
What does conservation of energy mean?
Total energy increases
Total energy decreases
Total energy stays the same
If the marble had 6.9 J of (potential) energy at the top of the hill and 5.4 J of (kinetic) energy at the bottom of the hill, was energy conserved and why?
Yes because the total energy stayed the same
Yes because the total energy changed
No because the total energy stayed the same
No because the total energy changed
If the marble hits a basketball which makes the tennis ball roll across the lab table, what kind of energy transfer happened?
kinetic-potential
kinetic-kinetic
kinetic-electrical
kinetic-thermal
If the 1.2 kg basketball rolls at 3 m/s, what is it's kinetic energy?
2.7
5.4
3.6
9
What does conservation of energy mean?
Total energy increases
Total energy decreases
Total energy stays the same
The marble had 5.4 J of kinetic energy and then hit the stationary basketball. The basketball started rolling and the marble stopped rolling. The rolling basketball now has 5.4 J of kinetic energy. Was energy conserved and why?
Yes because the total energy stayed the same
Yes because the total energy changed
No because the total energy stayed the same
No because the total energy changed
