Law of Conservation of Energy
Where on a roller coaster does kinetic energy exceed potential energy?
The drops
A completely still hockey puck on an ice rink has _______ kinetic energy (a small amount, a large amount, zero)
Zero
_________ potential energy is stored energy due to gravitational field
Gravitational
When a pendulum is swinging, at the very lowest point it has the most _______ energy
Kinetic
Resistance caused by contact from one surface to another
Friction
A roller skater stops generating forward momentum, standing perfectly still upright. Why is it that they drift to a stop on a flat surface instead of continuing forward forever?
Friction
