|
Work done |
Work done = force × distance (along the line of action of the force) |
|
|
Force applied to a spring |
Force applied to a spring = spring constant × extension |
|
|
Moment of a force |
Moment of a force = force × distance (normal to direction of force) |
|
|
Pressure |
Pressure = force normal to a surface ÷ area of that surface |
|
|
Distance traveled |
Distance traveled = speed × time |
|
|
Acceleration |
Acceleration = change in velocity ÷ time taken |
