What is the relationship between friction and momentum?

Friction affects momentum because as friction increases, momentum decreases. Friction is always at work to slow down moving objects.

What is the momentum conservation equation?

The formula for the Law of Conservation of Momentum is p=p’ or m1v1+m2v2=m1v1’+m2v2′. This equation shows us that the sum of the momentum of all the objects in the system is constant.

What does it mean for energy and momentum to be conserved?

conservation of momentum, general law of physics according to which the quantity called momentum that characterizes motion never changes in an isolated collection of objects; that is, the total momentum of a system remains constant.

How do you find friction using momentum?

F=μN where N is the magnitude of the force of gravity perpendicular to the surface (called the Normal Force). μ is dependent on the surface material and the material of your object, larger μ means a greater force of friction.

How do you find total momentum?

Since the two colliding objects travel together in the same direction after the collision, the total momentum is simply the total mass of the objects multiplied by their velocity.

How does Newton’s 3rd law of motion relates to the law of conservation of momentum?

By starting with Newton’s third law, for every force there is an equal and opposite force, we can derive conservation of momentum, which tells us that a change in momentum in one of two objects colliding is equal and opposite to the change in momentum in the other colliding object.

How can both energy and momentum be conserved?

Elastic collisions are collisions in which both momentum and kinetic energy are conserved. The total system kinetic energy before the collision equals the total system kinetic energy after the collision. If total kinetic energy is not conserved, then the collision is referred to as an inelastic collision.

How does a dominoes knock down?

A chain of dominos of increasing size makes a kind of mechanical chain reaction that starts with a tiny push and knocks down an impressively large domino. See http://arxiv.org/abs/physics/0401018 for a sophisticated discussion of the physics.”.

Why do dominoes store more energy than other objects?

That taller, heavier domino stores even more potential energy, and that energy will continue to mount so long as each falling domino’s kinetic energy can overcome the potential energy of their more massive neighbors.

How powerful is a dominoes?

Dominoes: More Powerful Than You Think Physicist shows that a short sequence of dominoes can topple skyscraper-sized block. In this image, the National Dutch Science Quiz starts a domino chain reaction that will topple the towering 26-foot tall, half-ton domino to the left.
