Final 2024 Flashcards
How do you get displacement from a velocity vs time graph?
Find the area on the graph
How do you find the velocity on a position vs time graph?
Find the slope of the line
What is the difference between a vector and a scalar?
A vector includes the direction
How do you find the average velocity?
Displacement/Time
How do you find acceleration?
Change in velocity/time ((v2-v1)/(t2-t1))
What is the formula for speed?
Distance/Time
How do you find displacement in accelerated motion?
Displacement = v1 * time interval + (acceleration * time interval squared)/2
What is the velocity and displacement relationship?
v2 squared = v1 squared + 2 * acceleration * displacement
What is Newton’s 1st Law?
If an object has zero net force, then it will have a constant velocity
What is Newton’s 2nd Law?
F = ma, or a = F/m
What is Newton’s 3rd Law?
If two things interact, the force by the first on the second has the same magnitude as the force by the second on the first, but the directions are opposite
Every action has an equal and opposite reaction
What is the formula for centripetal acceleration?
Centripetal acceleration = speed * time squared/radius
What is the formula for the time of one revolution?
1/frequency, or total time/amount of revolutions
What is the formula for speed in circular motion?
2 * pi * radius/time
What is the formula for centripetal force?
Mass * centripetal acceleration
