Energy, Force, Motion, Work
This is the ability to do work or cause change
Energy
This is the energy of movement
Kinetic energy
These two types of energy are the sum of kinetic and potential energy.
Thermal and mechanical energy
This is the kind of energy transformation that takes place after a train speeds by and the rails feel hot.
Kinetic to thermal
This is the unit we use to measure force.
Newtons
How much kinetic energy does a 40 kg car have when travelling at 20 m/s?
8000 J
An object is in this when its position changes relative to another object
This type of energy depends on mass and height.
This type of energy is most closely related to temperature.
Thermal energy
This is what happens when one kind of energy becomes another kind of energy.
This is the unit we use to measure work.
Joules
How much work is being done when a force of 45 N was applied to move a box 10 meters?
450 J
Forces are considered to be this when the net force is anything but zero.
Unbalanced
These are two things that kinetic energy depends on.
Mass and speed
These are three kinds of potential energy.
Chemical, nuclear, electrical, elastic, gravitational
This law states that energy cannot be created or destroyed.
The Law of Conservation of Energy
This is the unit we use to measure power.
Watts
How much potential energy does a 51 kg book have sitting on top of a table 3 meters above the ground?
1499.4 J
This is the amount of work done when 15 N of force are applied over a distance of 6 meters.
90 J
This is the amount of kinetic energy a 5 kg ball has flying through the air at 2 m/s.
10 J
This is when small nuclei combine to form a larger one.
This is what happens when energy moves from one object to another.
Transfer
This is the unit we use to measure height.
Meters
How much mechanical energy does a box have if it has 42 J of potential energy and 17 J of kinetic energy?
59 J
This is the amount of power output when 50 J of work is done over 2 seconds.
25 W
This is the value of acceleration.
9.8
These are the types of energy that you acquire when you eat a bowl of hot vegetable soup.
Thermal and chemical energy
Energy cannot be created or destroyed, it can only be this.
Transferred or transformed
This is the unit we use to measure energy.
Joules
Calculate the net force on a box if Courtney is pushing from the left with a force of 14 N, Hailey is pushing from the right with a force of 63 N, and Amber is pushing from the left with a force of 51 N.
