SPEED
This is the formula to calculate speed.
What is d / t?
If it took 4 seconds for our car or robot to go the full length of our raceway, this is the speed of the car or robot in meters per seconds.
This is how many meters per second a car gains every second if it has an acceleration of 3 meters per second squared.
What is 3 meters per second?
These are the units of energy.
What are joules?
These are the units of work.
What are joules?
This is an example of the units of speed.
What is miles per hour, meters per second, kilometers per hour...?
Answers may vary.
4 meters per sec north is an example of this.
What is a velocity?
The delta in "delta v" stands for or means this.
What is change in?
Potential energy + kinetic energy always equal this.
What is mechanical energy (or 100 %)?
45,000 joules of work is this many kilojoules.
What is 45 kJ (kilojoules)?
This is the formula to calculate time when given speed and distance.
What is distance / speed?
This was the length of our raceway.
What was four meters?
These are the units of acceleration.
What are meters per second squared?
Potential energy has to do with this specific variable of an object.
What is its height (or position)?
This is how work is related to power.
What is power equals work / time?
What is work equals power x time?
What is time equals work / power?
What is both have joules for units?
This is the formula to calculate distance when given speed and time.
What is speed x time?
We calculated this by taking delta v / time.
What is acceleration?
This is what delta v equals.
What is final velocity minus initial velocity?
These are the three types of calculated energy we discussed in class.
What is mechanical, potential, and kinetic?
This is what one joule equals.
What is a Newton x meter?
What is a (kg x meter squared) / second squared?
This variable separates speed from velocity.
What is direction?
This robot helped us with the Raceway of Science.
What is a Sphero or Bolt?
A negative acceleration is called this.
What is deceleration?
Kinetic energy is the energy in these types of objects.
What is moving?
This is the formula to calculate work.
What is work equals force x distance?
