A Change in position.
The rate of change in distance.
What is speed?
This is described by knowing the speed and direction.
What is velocity?
The change in position between the starting point and the ending point.
What is displacement?
A rocket accelerates at 12 m/s for 8s. If it starts at rest, what is its final speed? 2
The rate of change in velocity.
What is acceleration?
Acceleration can occur in these three ways.
What is speeding up, slowing down, and changing direction.
Acceleration can be calculated using this equation.
When you are speeding up you have this type of acceleration.
What is positive acceleration?
This is a train's acceleration when its speed increases from 7m/s to 18 m/s over a period of 120 s.
The measure of how hard it is to stop the object.
What is momentum?
Momentum is changed when you exert this on an object.
When a toy truck collides with a toy car, the momentum of these is the same before and after the collision.
What is the truck plus the car?
The momentum of a compact car with a mass of 725 kg moving at 30 m/s.
What is 21,750 kgxm/s?
The velocity of an object with a momentum of 600 kgxm/s.
What is 12 m/s?
This is the amount of matter in an object.
What is mass?
What are the units used to measure momentum?
m/s 2
What are the units used to measure acceleration?
What are the units used to measure mass?
This is the velocity of a 10-kg object with a momentum of 50 kgxm/s.
Acceleration involves a description of these.
What is speed and direction.
