change in an object position relative to a reference place
Motion
distance and direction of the object change in position
Displacement
distance an object can travel per unit
Speed
How do you calculate total distance?
Add all your distances together.
What needs to be included in you answer for displacement?
distance and direction
Displacement can be calculated in the same direction. True or False?
True
You subtract displacement if they are going in the opposite direction. True or False?
True
You cannot directly calculate if they are not the same or in opposite directions. True or False?
True
What is the equation for speed?
speed=distance divided by time
The speed of an object and the direction of its motion.
Velocity
An object is the product of its mass and velocity.
momentum
The rate of change of velocity
acceleration
Acceleration toward the center of a curved or circular path.
centripetal acceleration
What is the difference between speed and velocity?
velocity has distance
Is it possible to have a constant speed with a change in velocity?
yes
How do you calculate momentum?
p=mv
What are the units for momentum?
kg*m/s direction
What is the unit for mass?
kg
What are the units for velocity?
m/s direction
