Term

Definition
A Scalar quantity has only magnitude
A Vector quantity has magnitude and direction.
The absolute value of a vector is a scalar 


Term
Write out the formula for average speed 

Definition
total distance covered  time interval 


Term
write out the formula for acceleration 

Definition
change in velocity  time interval (in a double unit such as seconds squared or seconds per hour) 


Term
The distance traveled by a uniformly accelerating object starting from rest is formulated as (distance traveled) 

Definition
Distance traveled = 1/2 (acceleration X time X time)
d = 1/2g t^2 


Term
Write out the formulas (3) for velocity 

Definition
v = gt = (BA)/time = a x t
g = rate of acceleration 


Term

Definition
Every object continues in its state of rest, or of uniform motion in a straight line, unless it is compelled to change that state by forces impressed upon it; Newtons 1st Law. 


Term
What is Newtons First Law? 

Definition
The Law of Inertia; Every object continues in its state of rest, or of uniform motion in a straight line, unless it is compelled to change that state by forces impressed upon it. 


Term
What is a force simply defined as? 

Definition


Term
What is the formula for and what does mechanical equilibrium mean? 

Definition
When the net force on something is zero
EF = 0
(^ not actually E, but summation) 


Term
What are the two names for the force that acts to keep a book on a table per se? 

Definition
The support force, or normal force 


Term

Definition


Term

Definition
Displacement is a vector vs Distance is a scalar 


Term
Distinguish between constant position, constant velocity and constant acceleration in respect to displacement, velocity, and acceleration 

Definition
constant position D=D V=0 a=0
constant velocity D= v x t V = constant A = 0
Constant acceleration D = (1/2a)(t^2) V = a x t a = constant 


Term

Definition
No other forces are acting on it except for gravity, happens the instant an object “leaves your hand”; constant acceleration 


Term

Definition
The description of how things move 


Term
What causes acceleration? 

Definition


Term
What is the formula for gravity? 

Definition
mg
m = mass g = acceleration rate (9.8 m./s^2 or 32 ft/s^2 


Term
What is weight a measurement of? What is the pound unit of? 

Definition


Term
What is the formula for net force? 

Definition
netF = ma
mass x acceleration 


Term

Definition
In a net force, the direction of the force and the direction of the acceleration are equal; the summation of forces 


Term
What is a newton? (the formula for one) 

Definition
Newton = kg x m/s^2
1 N = 1kg x m/s^2
m = meter
