After your workout, itâs time to refuel with: 1  Fluids. Drink water, of course. 2  Carbohydrates. You burn a lot of carbohydrates â the main fuel for your muscles â when you exercise. 3  Protein. Eat things with protein to help repair and grow your muscles, including a whole grain bagel, baked potato, peanut butter sandwich, etc.
inertia - (physics) the tendency of a body to maintain its state of rest or uniform motion unless acted upon by an external force. natural philosophy, physics - the science of matter and energy and their interactions; his favorite subject was physics.
Inertia is dependent on the mass of the object being considered, and sometimes by its momentum - depending on how we are using the term. Recall that inertia is the resistance â¦of a body to a change in motion. (A body at rest tends to remain at rest unless acted on by an outside force. And, a body in motion tends to remain in motion unless acted on by an outside force.)   We think of something massive as resistive to being moved. That's inertia.
