Term or Question | Definition or Answer |
---|---|
What is the definition of Acceleration? | “how quickly is velocity changing” = rate of change in velocity (m/s^2) |
What is the definition of Velocity? | “how fast” = rate of change in position (m/s) |
What is the definition of Displacement? | “how far” = change in position (meters) |
Distance: (identify as vector or scalar; give units) | scalar - meters |
Displacement: (identify as vector or scalar; give units) | vector - meters |
Velocity: (identify as vector or scalar; give units) | vector - m/s |
Speed: (identify as vector or scalar; give units) | scalar - m/s |
Acceleration: (identify as vector or scalar; give units) | vector - m/s^2 |
Time: (identify as vector or scalar; give units) | scalar - seconds |
Mass: (identify as vector or scalar; give units) | scalar - kilograms |
Energy: (identify as vector or scalar; give units) | scalar - joules |
Power: (identify as vector or scalar; give units) | scalar - watts |
