Newton's Laws: Forces and Motion. A force is a push or a pull. A force is a vector : it has a magnitude and a direction. Forces add like vectors, not like scalars. Example: Two forces, labeled. same magnitude. F1 and F2, are both acting on the same object. The forces have the.
Momentum is calculate using the formula: P = m (mass) x v (velocity) Force can defined as something which causes a change in momentum of a body. Force is given by the celebrated newton's law of motion: F = m (mass) x a (acceleration) Impulse is a large force applied in a very short time period.
Force and Friction. ∑ = m1a1 = m2a2.
