## Which of the following will change the momentum of a moving object select all that apply?

Momentum of an object is defined as quantity of a motion an object has. It mathematically calculated as product of mass and velocity of the object. From the above equation we can say that the change in both mass and velocity will change the momentum of a moving object.

## What will change the momentum of a moving object?

A force acting for a given amount of time will change an object’s momentum. If the force acts opposite the object’s motion, it slows the object down. If a force acts in the same direction as the object’s motion, then the force speeds the object up. Either way, a force will change the velocity of an object.

## Can the momentum of an object change?

Impulse: At constant velocity the momentum of an object remains constant but if that object comes in contact with another object there is a change in momentum (acceleration or deceleration) that is related to the time of contact. This relationship is called impulse.

## What affects the momentum of an object?

What two factors affect an object’s momentum? Momentum is affected by the mass of the object and its velocity (or speed). Momentum is mass in motion!

## Can you change the mass of an object?

Mass is the amount of matter in an object and does not change with location. The only way to change the mass of an object is to take away part of the object or add to it. An object with a mass of one kilogram (kg) has the same mass on another planet, like Jupiter.

## Why would mass change?

The mass of an object does not change with speed; it changes only if we cut off or add a piece to the object. Since mass doesn’t change, when the kinetic energy of an object changes, its speed must be changing. Special Relativity (one of Einstein’s 1905 theories) deals with faster-moving objects.

## How can we change density?

What can change density: 1) Adding or removing mass but not changing the volume. Increasing or decreasing temperature changes the volume but not the mass. Increasing or decreasing pressure will change the volume but not the mass.

## What are the two factors that make up density?

The size, mass, and arrangement of atoms affect the density of a substance. How might these factors work together to cause a substance to have a high density? A substance with smaller more massive atoms that are close together is going to have a higher density.
