Force means that a _____ or a _____ are applied to an object in order to move it from one place to another.
What is a push or a pull?
100
This is a type of force that attracts objects to one another.
What is a gravity?
100
The process of moving an object requires this.
What is Work?
100
Name two types of friction
What is static and dynamic friction?
100
Define Energy.
What is the capacity to do work?
200
This is how quickly an object changes speed.
What is acceleration rate?
200
Gravity is a ____that God created.
What is force?
200
Work is measured in this unit.
What is Joules?
200
Define friction.
What is when two things rub together?
200
Name the two categories of energy.
What is potential and kinetic energy?
300
This is the amount of force and can be measured
What is magnitude?
300
Gravity pulls things in this direction.
What is straight down.
300
True or False: Moving an object a short distance takes less work than moving it a long distance as long as you change the force you use.
What is False: The force must stay the same.
300
This is the frictional force at the very start of the movement.
What is static friction?
300
This is stored energy.
What is potential energy?
400
Magnitude is measured in this unit.
What is Newtons?
400
As an object gets farther away from the earth, the pull of gravity is this.
What is less?
400
These two things determine the amount of work needed to move an object.
What is Mass and Distance.
400
This the frictional force when an object is moving.
What is dynamic friction?
400
This is the energy of motion.
What is kinetic energy?
500
This is the formula used to calculate force
What is force = mass X acceleration?
500
Since gravity is a force it has this.... 2x - it can be measured in this unit.
What is magnitude and Newtons
500
Work is defined as force applied to an object over a certain _________.
What is distance?
500
This determines how slippery two materials are when they are in contact with each other.
What is the coefficient of friction?
500
This is the most common type of potential energy.
What is gravitational potential energy?
