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 m x v2?
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?
Two projectiles launched at complementary angles will both travel this equal dimension.
What is distance (or range)?
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?
When analyzing projectile motion, we must analyze these two independent motion vectors.
What is the horizontal motion and the vertical motion?
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 x2?
This is the other dimension must we take into account when analyzing projectile motion.
What is time (the amount of time the projectile is in the air)?
This property of two colliding objects does not change before or after an elastic or inelastic collision.
What is the masses of the objects?
