• Weight is the product of mass and acceleration due to gravity.
  • Speed is scalar while velocity is vector. They can be both calculated by dividing the distance travelled by the time it took to travel.
  • Acceleration is the rate of change of velocity. It is the difference of the final and initial velocity divided by the time.
  • According to the second law of motion, Force is equal to the product of the mass and acceleration.
  • Momentum is the Kinetic Inertia of a moving object. It can be calculated by multiplying the mass and the velocity of the object. Momentum is conserved.
  • Impulse is the change in momentum.
  • Torque is the force for rotational motion. It is computed by multiplying the force applied and the length of the lever arm.
