Motion
The SI Unit for measuring Length is...
Meters
What is Newton's First Law of Motion?
An object at rest will stay at rest and an object in motion will stay in motion unless acted upon by an Unbalanced Force.
What is the Momentum Equation?
P = M*V
What Is Conserved (saved) In all collision Types?
Momentum
What two Factors affect Universal Gravitational Force?
Mass
Distance (Radius)
This type of motion is constant and unchanging, it is non-accelerated
Uniform Motion
What is needed to change the motion of an object?
An Unbalanced Force
If two objects are traveling at the same Velocity,
But object "A" has twice the mass of object "B",
which has Less Momentum?
Object "B"
Name the Collision type...
Two pieces of clay hit and stick together.
Perfect Inelastic Collision
What Two Factors Affect Electrostatic Forces?
Charge
Distance (radius)
A Scalar measurement becomes a Vector Quantity when it includes...
Direction
What is Newton's Second Law of Motion?
Acceleration = Fnet / Mass
Is Momentum a Vector or Scalar Quantity
"Vector"
Momentum includes Velocity,
Velocity includes direction.
If the total Initial Momentum in a System is 5,000Kg.m/s
What will be the Total Final Momentum?
5,000Kg.m/s
What is the Equation for Universal Gravitational Force?
FG = (M1 * M2) / (r)2
Lando Norris drives 30 kilometers West from his house and then 50 Kilometers East before stopping. What is his Displacement at the end of his drive?
20 km East
If someone is pushing a car of mass 2000 kg with a force of 2000N, what is the acceleration of the car?
2000N / 2000kg = Acceleration
Acceleration = 1m/s2
What are the two ways (equations) to solve for and IMPULSE?
ΔP = M * ΔV
&
I = F * Δt
List the For Characteristics of an Inelastic Collision...
Bounce Off
Lose Energy
Change Shape
Save Momentum
How many times Stronger or Weaker would the force between two Planets be if the Distance between them AND the Masses were doubled?
New FG =
1 times as strong
or
The same
What does the “Δ” in the term “Δx” stand for or mean?
The Change in...
Or
Final - Initial
Why are two Free Body Diagrams needed to analyze Newton's 3rd law?
Equal but opposite reactions are acting on opposite objects. Two F.B.D.s are needed to show forces on each object.
If the amount of time an Impulse (Change in momentum) takes to occur is Decreased (happens faster) what happens to the force experienced?
The Force Increases
What will be the Final Velocity of two Football players be After they tackle each other? (they stick together)
M1= 60kg M2= 40kg
V1i= - 5m/s V2i= +2.5m/s
VF = -2m/s
If the Original Electrostatic Force Was 100N,
What will the New Force be if Both of the Charges are Doubled and the Distance is Cut in Half?
New FE = 1,600N
