Ch 2 Equations
100
This equation is the way to calculate avg. speed.
What is distance over time.
100
This is the rate at which velocity changes. it happens when speed, direction or both change.
What is acceleration.
100
This is a push or pull.
What is force.
100
An electric insulator is usually this material.
What is rubber or plastic.
100
this is how work is calculated.
What is force times distane
200
This equation is how to calculate avg. acceleration.
What is final velocity minus starting velocity over time.
200
Electric current is this.
What is the rate at which electric charges pass a given point.
200
This is kinetic energy.
What is the energy of movement.
200
These affect the electrical force between two objects.
What is charge and distance.
200
Energy over time is how you calculate this.
What is power
300
F=ma is the equation for this.
What is force
300
This is a device that helps do work by changing the magnitude and/ or direction of an applied force
What is a machine.
300
this is a material through which electric charges move freely.
What is an electric conductor.
300
This is the buildup of electric charge on an object.
What is static electricity.
300
Kinetic energy is one half mass times velocity squared. If a foal weighs 100 lbs. and moves at 8 m/s, then how much kinetic energy does it have

What is 9.8 meters per second.
400
This is an electromagnet.
What is a solenoid wrapped with electric wire.
400
This is the rate at which work is done. It is also the rate at which energy is transformed.
What is power.
400
These are what move around to change the charge of an object.
What is electrons.
400
Mass in kilograms times gravity on Earth (9.8 m/s) times length from ground is the equation for this.
What is gravitational potential energy.
500
This is the way you calculate gravitational force.
What is Force equals mass times gravity.
500
This is gravity.
What is the force of attraction between objects due to their mass.
500
This is the motion of a body when the only force acting on that body is gravity.
What is free fall.
500
These are how objects gain or lose electrons.
What is friction, contact or conduction, induction.
500
This is the equation for mechanical efficiency
