Unit Three Flashcards
What is the formula for speed
S=d/t
On a distance time graph what is the X and y axis and what would the slope tell you
Distance = y
Time= X
Slope tells you speed
What is the formula for distance
D = s X t
What is terminal velocity
When objects stop accelerating and fall at a constant speed
How is terminal velocity related to surface area and mass
No relation to mass
Larger surface area. Slower terminal velocity
What is the formula for acceleration
A= f/m A= s/t A= vf - vi ------ T
On a speed time graph what does the slope give you
Acceleration
What is inertia
Tendency of objects to keep doing what they are doing, resist change
What is meant by the term equilibrium and what can an object in equilibrium be doing
All forces are equal and constant speed or not moving
If an object has a net force other than zero what is happening
Accelerating or decelerating
Is a car moving around a circular track going at a constant speed
Yes
What is the relationship between force and acceleration
When force increases
Acceleration increases
What is Newton’s second law
F = m X a
What are the units for m, f, and a
M = kg F= n A= m/s/s
What is Newton’s third law
For every action there is an equal and opposite reaction
