An object in motion will stay in motion or an object at rest will stay at rest
What is Newton's first law of motion
Distance divided by time
The study of matter and energy
What is Physics
Brings about change in matter by putting it into motion or bringing about a physical change.
What is energy
Discovered objects fall at the same speed
Who is Galileo
More force must be applied to move a larger object the same distance as a smaller object
What is Newton's second law of motion
This includes both speed AND direction
what is velocity
The time it takes for a pendulum to complete a full swing
What is a period
known as the energy of motion
what is kinetic energy
The screw is an example of this simple machine
what is an inclined plane
the gravitational pull between 2 objects directly related to this
what is mass
Change in velocity/change in time
what is acceleration
two points along the axis of an ellipse
what is foci
occurs when a SMALL amount of mass release a LARGE amount of energy
what is a nuclear blast
who is watt
For every action there is an equal and opposite reaction
What is newton's third law of motion
force times time on an object calculates this.
impulse
Attraction between two objects
In Einstein's equation of relativity, the E stands for this
What is energy
186,000 miles/second
what is the speed of light?
property of matter that is resistant to change
what is inertia
actual mechanical advantage/theoretical mechanical advantage calculate this
the shape of Earth's orbit around the sun
what is an ellipse
the amount of light energy a planet twice as far from the sun receives
what is a fourth
A pulley that changes the pull direction but not the effort load.
A fixed pulley
