What is momentum, and why is it such an important quantity in physics? Discover how momentum is related to force, why momentum is conserved, and how the same change in momentum (impulse) …

Momentum can explain—or predict—what happens when objects with different masses and velocities collide with one another. Let's bump our way into this important and relevant concept.

Momentum is the product of an object's mass and its velocity. It is a vector quantity. Newton's second law can be rearranged to reveal that the net force on an object is equal to the rate of change of the …

Momentum is a vector quantity that has both direction and magnitude. Momentum is symbolized as the letter P and precisely momentum is the mass times the velocity.

Describe an object's momentum in terms of its mass and velocity. Relate a system's change in momentum to the product of the net force exerted on it and the time interval during which the force acts.

Impulse is a change in an object's momentum. The impulse experienced by an object is equal to the net force acting on the object multiplied by the length of time the force acts (Δp = ΣFΔt).

Opa. Algo deu errado. Por favor, tente novamente. Ah não, parece que ocorreu um erro. Você precisa atualizar. Se o problema persistir, fale conosco.

Conservation of momentum is actually a direct consequence of Newton's third law. Consider a collision between two objects, object A and object B. When the two objects collide, there is a force on A due …
