CH2.1 Flashcards
motion
the action or process of moving or being moved
displacement
the movement of something from its place or position
speed
the rate at which someone or something is able to move
displacement can be calculated in the same direction true or false?
true
you subtract displacement if they are going the opposite direction
true
you can not directly calculate displacement if they are not in the same or opposite direction
true
how do you calculate speed
distance divided by time S=D/T
how do you calculate momentum
p=mv
how do you calculate velocity
v=mp
what is the difference between speed and velocity
velocity has a direction
velocity
the speed of an object and the direction its moving
acceleration
the rate of change in velocity
centripetal acceleration
acceleration toward the center of a curved path
what is the unit for mass
kg
is it possible to maintain a constant speed with a change in velocity
no
