Momentum and Impulse

Impulse (I) is defined as the product of the average force (F) and the time interval (delta t) over which it acts.

Since impulse is force (kg * m/s^2) multiplied by time (s), the units are kg * m/s.

Impulse is a vector quantity because it is the product of a vector (force) and a scalar (time).

The impulse-momentum theorem states that the impulse applied to an object is equal to the change in its momentum.

Kinetic energy is given by KE = p^2 / (2m), where p is momentum. Thus, kinetic energy is directly proportional to the square of the momentum.

Momentum is defined as the product of an object's mass and its velocity. Option D represents this standard physical definition.

Momentum is a vector quantity because it is the product of a scalar (mass) and a vector (velocity), meaning it has both magnitude and direction.

Since momentum is mass times velocity, the SI unit is the unit of mass (kg) multiplied by the unit of velocity (m/s), resulting in kg m/s.

Momentum is defined as the product of mass and velocity. Impulse is the product of force and time, while work is force times displacement.
