Work
This is the amount of force applied over a certain distance or Blank = Force x distance
Work
This the rate at which work is done or Blank
power
This is the amount of stored energy in an object based on it's height or Blank = m * g * h
Potential Energy (PE)
What is kinetic energy?
The energy of motion
What is a change over time called?
A rate
This is the unit that Work is measured in.
Joule
This is the unit that power is measured in blank.
Watts
This is the unit that PE is measured in.
Joules
Does a car store kinetic energy?
no
The rate of change in speed or direction is called?
acceleration
This is another way to express the unit Joules for work.
Newton
This happens to power when you increase the amount of work done.
increasing your power, increasing the power, increasing powe
If you double an object's height, this happens to your Potential Energy.
doubling your Potential Energy
True or False: does bowling use Kinetic energy?
True
What is the acceleration due to earth's gravity?
9.8 m/s/s or m/s^2
The direction of displacement and the direction of the force applied are in the SAME DIRECTION.
positive value
This happens to power when you increase time.
decreasing power, decreasing your power, decreasing the power
Before an object begins to move, the Total Mechanical Energy an object has is equal to its blank
Potential Energy
Sam is standing in line for a new xphone. Does he have kinetic energy?
no
On top of a roller coaster what energy do you have?
Potential
The direction of the displacement and the direction of the force are PERPENDICULAR TO EACH OTHER. This means that the amount of work done will be blank.
0 Joules
If I do 2000 Joules of work in 5 seconds, I produce this amount of power.
400 watts?
An object moves down a ramp without friction. The object loses potential energy and gains this type of energy.
Kinetic Energy.
A rocket is flying in a straight line. Does it have Kinetic energy?
yes
What type of energy does a trampoline have when you are standing on it?
Elastic potential energy66
