Work
This equation can define work
What is force x distance?
This the equation for acceleration as defined by N2LM.
What is
a = F/m
An object moving in this path shape is what defines Uniform Circular Motion.
What is a circle?
We call this kind of energy "stored energy".
What is Potential Energy
For an object to have KE, it MUST have this.
What is velocity?
Momentum has this unit.
What is kg x m/sec?
This equation also defines work
What is
DeltaKE
?
The acceleration of a less massive object requires less of this than a more massive object.
What is force?
Centripetal acceleration is a function of these two (2) variables.
What is velocity and radius (of the circular path)?
This is how we describe what happens to energy of a falling object
What is as an object falls, its potential energy decreases while its kinetic energy increases, conserving the total mechanical energy?
The equation that is used determine the amount of KE an object has.
What is (.5) x mass x velocity2?
This is the equation for momentum.
What is mass x velocity?
In order to have done work on an object we had to do this to it.
What is move it?
Acceleration multiplied by mass equals this.
What is Force?
The centripetal force of an object also includes this dimension of the obect.
What is it's mass?
A description of how height affects potential energy?
What is the higher an object is, the greater its potential energy, as it is directly proportional to height?
A Formula One (F1) car and a fully loaded dump truck have the same velocity. But the dump truck has more KE because it has a lot more of this.
What is mass?
If the velocity of an object triples, then its momentum went up this much.
What is 3x?
If we're calculating the velocity of an object using KE, we better remember to do this after we double the KE and divide it by mass.
What is take the square root?
This is the unit for work and energy.
What is Joule?
A Formula 1 car and a dump truck both produce 800 horsepower of force, but the Formula 1 car accelerates much faster because of this.
What is the less mass of the F1 car?
When the velocity of an object is tripled, then both its centripetal force and acceleration increase by this much.
What is nine times (9x)?
This is the equation for PE.
What is mass (x) gravity acceleration (9.8) (x) height?
As a rock falls to the Earth, it gains KE due to gravitational acceleration, and its PE is getting less and less. This is because of the Law of this.
What is the Law of Conservation of Energy?
A type of collision where two objects collide and both scatter in different directions?
What is an elastic collision?
A joule breaks down into these units.
What is a kg x meter per second2?
This force is responsible for an object's acceleration in freefall.
What is gravity?
As the radius of the circle increases, the centripetal acceleration and centripetal force must do this.
What is decrease?
These two (2) variables determine potential energy in a spring or compression.
What is the spring (or force) constant, k, and the amount of stretch or compression squared, x2?
The Law of Conservation of Energy states we can only do this and cannot do that.
What is we can only transform energy and we cannot create or destroy energy?
This property of two colliding objects does not change before or after an elastic or inelastic collision.
What is the masses of the objects?
