The scientist credited with the development of the three laws of motion.
Who is Isaac Newton
100
A train traveling at constant speed in a straight line - with explanation.
What is balanced because it is a constant speed in a straight line?
100
If two people are arm wrestling and one is pushing with 50 Newtons of force while the other is also pushing with 50 Newtons of force this will happen.
They will tie - not move - because the forces are equal and in opposite directions
100
A push or a pull
What is Force?
100
The distance between the same point on two successive waves; distance from crest to crest or trough to trough for two consecutive waves.
What is wavelength
200
Equal force that does not cause a change in the object’s motion
What is Balanced Force
200
Unbalanced force
200
The net force if you are swimming forward with a force of 100 Newtons while the water is pushing back with a force of 50 Newtons
50 Newtons forward
200
The force that attracts a body toward the center of the earth, or toward any other physical body having mass.
What is gravity?
200
The height of a wave measured from rest to the top of the crest or bottom of the trough of the wave - often used to describe the volume of sound or intensity of light.
What is Amplitude?
300
Unequal force that causes a change in an object’s motion
What is an Unbalanced Force
300
If you push a shopping cart and then let go, inertia states that it will
What is keep moving until an unbalanced force (friction and gravity) stops it.
300
Net force and direction
100 Newtons to the left
300
The sum of all the forces acting on an object within a system; includes both magnitude and direction
What is Net Force?
300
The number of waves that pass a given point in a specified amount of time (usually 1 second), measured in hertz (Hz); the pitch of sound or the color of light.
What is Frequency?
400
An object at rest stays at rest or an object in motion stays in motion unless acted upon by an unbalanced force.
What is Newton's 1st Law
400
An object at equilibrium would be acted on by
What is a balanced force?
400
The Net force and direction
20 Newtons to the right
400
A table being pushed forward is being acted on by these forces.
What is gravity and friction?
400
A type of wave in which the particles oscillate perpendicular to the direction in which the energy propagates.
What is a transverse wave?
500
An object’s tendency to resist a change in motion
What is Inertia?
500
The earth's rotation around the sun - with explanation
What is an unbalanced force because it changes direction
500
A fish is swimming upstream and pushing on the water with a force of 20 Newtons. The current is pushing back with a force of 10 Newtons. If the water begins pushing at 15 Newtons the fish will
What is slow down because it would need more force to keep going?
500
A skydiver will be acted on by these forces in these directions
Air resistance pushing upward and gravity pulling down
500
The range of waves that are propagated by simultaneous periodic variations of electric and magnetic field intensity.
What is electromagnetic wave?
