Physics Quiz 1 Flashcards
Unit of measure for velocity
Meters per second
What is velocity?
Distance traveled divided by the time necessary to cover that distance
(V=d/t)
What is acceleration?
Found by subtracting the initial velocity of an object from its final velocity and dividing that value by the time used, (a=vf-vo/t)
Unit of measure of acceleration
Meters per second squared
What is force?
A push, a pool, or other action that changes the motion of an object.
(F=ma)
Unit of measure of force
Newton
What is momentum?
Equal to the mass of the object multiplied by its velocity
P=mv
What is work?
An expression of the force applied to an object multiplied by the distance across which it is applied
(Work=fd)
What is the unit of measure for momentum?
Kilogram-meters per second
Unit of measure for work
Joule
What is power?
Equal to work divided by the time during which work is done.
p=work/t
Unit of measure for power
Watts
