Physics
The unit for force
What is a Newton?
A numerical measure of its inertia; a measure of the amount of matter in the object? m = Fg/g
What is the mass?
The formula to calculate speed
What is speed = distance/time?
This is a vibration that propagates as an acoustic wave through a transmission medium such as a gas, liquid or solid
What is sound?
The energy of motion
What is Kinetic energy?
An objects tendency to stay in motion or at rest
What is inertia
He is often referred to as one of the "Founding Fathers" of modern physics.
Who is Sir Isaac Newton
"Every object retains its state of rest or state of uniform straight line motion unless acted on by an unbalanced force"
What is Newton's First Law?
This law is a formulation of the law of conservation of energy in the context of thermodynamic processes.
What is the first law of thermodynamics?
The rate at which velocity changes
What is acceleration?
This is represented by the measure of energy transfer that occurs when an object is moved over a distance or W = Fd*cos(angle)
What is work.
The motion of an object when it is not touching anything and is experiencing no air resistance.
What is free fall?
This is a reaction in which the nucleus of an atom splits into two or more smaller nuclei
Fission
The unit for work and energy
What is the Joule?
The force of gravity on the object and may be defined as the mass times the acceleration of gravity, Fg = mg
What is weight?
The difference between speed & velocity
What is that velocity is a vector/has a direction?
Visible light, x-rays, and radio waves are all this type of energy
What is Electromagnetic?
The distance traveled by a car traveling at 40 km/h for 30 minutes
What is 20 km?
The mass (with correct unit) of an object that is traveling at 20m/s^2 and has a force of 10,000N
M = F/A
M= 10,000 / 20
M= 500kg
This scientific "principle" states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. OR F=M*A
What is Newton's 2nd Law
This is why astronauts would feel lighter on planets like Mercury and Mars.
What is the downward gravitational force on those planets is smaller (weaker).
This type of nuclear reaction fuels our sun
What is fusion?
