The study of physical science includes these two general areas of science.
What are physics and chemistry?
100
This is a metric unit of speed.
What is meters/second etc.
100
This is the metric unit of force.
What is the Newton (N)?
100
This is the metric unit of work.
What is the Joule? (or Newton-meter)
100
This is the metric unit of measure for energy.
What is the Joule? (or Newton-meter)
200
This is an educated guess made to answer a question or solve a problem.
What is a hypothesis?
200
These are the two factors used to determine an object's speed.
What are distance and time?
200
This is a description of a force.
What is a push or a pull on an object?
200
In order for work to be done, these two things must happen.
What is a force is applied and the object moves in the same direction as the force?
200
This term refers to energy that is stored.
What is potential energy?
300
This is the metric unit of measure for mass.
What is kilogram?
300
This is the difference between speed and velocity.
What is velocity has a direction.
300
Of Newton's laws of motion, this is the one that involves inertia.
What is Newton's First Law?
300
This is the purpose of a machine.
What is to change the direction or amount of force?
300
This is the factor which has the greatest effect on the amount of kinetic energy a moving object has.
What is velocity?
400
This is any part of an experiment that may change.
What is a variable?
400
This is how two objects may have the same speed, but different velocities.
What is they can be moving in different directions?
400
According to Newton's Second Law, these are the two factors that determine an object's acceleration.
What are force and mass?
400
This must be true about the amount of work that comes out of a machine compared to the work that goes in to the machine.
What is the work out must be equal or less than the work in?
400
This form of energy is released by vibrating objects.
What is sound?
500
If an object sinks in water, this may be said about its density.
What is density greater than one / greater than the density of water?
500
Acceleration can be positive, negative, or this...
What is centripetal?
500
Forces like friction and the floor pushing back against your weight are examples of this type of "R" force described by Newton's Third Law.
What are reaction forces? (or reactive)
500
This is the term that represents the number of times a machine multiplies force.
What is mechanical advantage?
500
This is the form of energy that is always produced when energy is converted from one form to another.
What is heat?
