The objects share a common final velocity.
Momentum is conserved, but kinetic energy is not.

Centripetal acceleration is v²/r.
A=100/20 = 5 m/s².

Torque depends on force, lever arm, and angle.
It is the rotational counterpart of force.

Acceleration is F/m = 4 m/s².
Change in velocity is at=4×3 = 12 m/s.

Torque magnitude equals force times perpendicular lever arm.
A larger moment arm produces greater turning effect.

The net force is 80-20 = 60 N.
Acceleration is 60/15 = 4 m/s².

Angular velocity describes how fast and in which sense an object rotates.
Its SI unit is rad/s.

Constant velocity means zero acceleration and zero net force.
The normal force therefore equals the person's weight, 600 N.

A measurement considered as one total amount takes a singular verb.
The entire distance is treated as one unit.

Work transfers energy when a force acts through a displacement.
Only the component of force along displacement contributes.

A habitual action is expressed with the simple present tense.
The third-person singular subject requires 'goes.'

Kinetic energy depends on mass and speed.
For translational motion, K=½mv².
