|---|---|---|---|---|
|
What is the definition of inertia?
An object at rest stays at rest; an object in motion stays in motion unless acted on by an outside force.
|
What is the equation for speed
Speed is equal to distance divided by time. (S=d/t)
|
What is Newton's 2nd Law?
Force is equal to mass multiplied by acceleration. (F=ma)
|
What is Newton's 3rd Law?
Every action has an equal and opposite reaction?
|
What is the definition of momentum?
A property of moving things.
|
|
What are the four categories to make a free body diagram?
Force of friction; force applied; Force normal; force weight.
|
What is three vector quantities?
Speed, velocity, acceleration.
|
What is one factor that can affect a free fall?
Air resistance.
|
What is a vector?
Any quantity that counts direction.
|
What is the equation for momentum?
P=mv
|
|
Who gave evidence behind Copernicus' ideas of a moving earth?
Galileo.
|
What is the difference between velocity and acceleration?
How quickly velocity changes is acceleration while velocity is the change in direction.
|
What is terminal velocity?
When direction is constant.
|
What can vectors show?
Displacement, velocity, acceleration, and force.
|
What is impulse?
An Impulse is something that makes velocity change.
|
|
What is Newton's first law of motion?
An object in motion stays in motion tends to stay in motion unless acted upon by an unbalanced force.
|
What would you measure forces in?
Newtons.
|
What is terminal speed?
When acceleration terminates.
|
What is a resultant in a vector addition diagram?
The net result of a combination of two or more vectors.
|
What is one way to decrease momentum over a short amount of time?
By decreasing time.
|
|
What is force net?
The sum of all forces.
|
What is distance?
Distance is the amount of space traveled; it is measured in meters (m).
|
How do you convert grams to kilograms?
Divide by 1000
|
Can forces act in the horizontal plane during the vector addition diagram?
No. The sum is zero.
|
What is he law of conservation of momentum?
In the absence of an external force, the momentum of a system remains unchanged.
