Energy
The unit used to measure energy
Joules
A pull or push that is applied to an object
Force
A runner travels at 5m/s
Speed
The relationship between electricity and magnetism.
Electromagnetism
An object’s resistance to a change in motion
Inertia
A roller coaster is sitting at the highest point of the track
Potential Energy
The unit used to measure force
Newton (N)
A runner travels at 5 m/s to the South
Velocity
Two objects with the same electric charge are placed near each other. What will they do?
Electrical Force
A hockey puck continues sliding across the ice until friction slows it down. Which law explains this?
First Law
A roller coaster is sitting at the highest point of the track
Kinetic Energy
The amount of matter in an object (weight)
Mass
A change in the velocity (speed, direction, or both) of a body
Acceleration
the attractive or repulsive force that is exerted between the ________ of a magnet and ___________ charged moving particles.
Poles
Electrically
Force is the product of mass and acceleration.
Second Law
As a roller coaster moves downhill, its potential energy decreases while its kinetic energy increases.
Law of Conservation of Energy
Two students push a box in opposite directions. One pushes with 50 N to the right and the other with 30 N to the left. The box moves to the right with the sum of 30 N. What do we call the sum?
Net Force
A force that opposes the motion of a body across a surface or through a gas or liquid
Friction
a region in space near a magnet or electric current in which magnetic forces can be detected.
Magnetic Field
For every action force, there is an equal but opposite reaction force.
Third Law
