Inertia and momentum are 2 concepts associated with the study of the motion of solid bodies. Momentum and inertia are both used to explain the current state of a body. Both are concepts related to the mass of the object.
Inertia: a characteristic of an object that resists changes to its state of motion.
- Explanation: Inertia is an intrinsic characteristic of the object related to its mass. Inertia tells you how much force it will take to cause a particular acceleration on the object.
- Inertia= if the body is at rest it will remain rest and it is moving it will continue moving in
Momentum: The resistance of an object to a change in its state of motion.
- Explanation: Momentum is a function of an object’s mass and velocity. Momentum is a measure of the kinetic energy of the object
- Momentum is the product of mass and velocity. momentum(P) = mass (M) × velocity(V)
