Question
Power is a dot product of
Options
- A
Force and Displacement
- B
Force and Velocity
- C
Force and time
- D
Work and time
Explanation
Power is the dot product of force and velocity.
Mathematically, this is represented as:
P = F • v
Where:
- P is power (the rate at which work is done)
- F is the force vector
- v is the velocity vector
- • denotes the dot product
This is not correct
