When a pendulum swings, at which point is potential energy at its greatest?
1
2
3
4
Which law? A gingerbread man kicks a football through some goal posts with their foot and their toes are left stinging...and possibly detached...
Newton's 1st Law
Newton's 2nd Law
Newton's 3rd Law
The white car hit the gray car, yet both cars were damaged. Why is that?
An object at rest will remain at rest unless acted on by an unbalanced force.
If you apply more force to an object, it will accelerate more.
For every action, there is an equal and opposite reaction.
Energy stored because of gravity is called:
Gravitational Potential Energy
Kinetic Energy
Mechanical Advantage
Chemical Energy
At which point does the ball has the greatest gravitational potential energy (GPE)?
A
G
D
C
G
Which would have the LEAST gravitational potential energy (GPE)?
A ball sitting on the ground
Moon viewed from the Earth
An airplane flying 30,000 feet above the ground
A rock sitting on top of Mt. Everest
What is kinetic energy?
The energy an object has due to its position or condition
The energy an object has due to its motion
The energy an object has due to its chemical composition
The energy an object has due to its atomic structure
When does an object have no kinetic energy?
When it's at rest.
When it's moving very slowly.
When the only force that's acting on it is gravity.
When it has no electrical charge.
Which is the best synonym for potential energy?
Stored energy
Energy of motion
Energy due to gravity
Mechanical energy
The ability of a system to do work; required for changes to happen within a system
Force
