# Quick Answer: What Factors Affect An Object’S Momentum?

## Does direction matter measuring momentum?

All moving objects don’t have momentum.

Direction does not matter when you are measuring momentum.

T 8.

Momentum can be transferred from one object to another..

## Where does momentum get its direction from?

In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object. where m is the mass and v is the velocity. The equation illustrates that momentum is directly proportional to an object’s mass and directly proportional to the object’s velocity.

## What is rate of change of momentum?

The rate in change of momentum of a body is equal to the product of mass of an object and acceleartion produced in it due to the force acting on the body provided that the mass of the object remains constant. It is given as: Rate of change of momentum = mass × acceleration.

## What factors could cause a change in the acceleration of a falling object?

When objects fall to the ground, gravity causes them to accelerate. Acceleration is a change in velocity, and velocity, in turn, is a measure of the speed and direction of motion. Gravity causes an object to fall toward the ground at a faster and faster velocity the longer the object falls.

## Which factor would not change the momentum of an object?

Notice that momentum does not just depend on the object’s mass and speed. Velocity is speed in a particular direction, so the momentum of an object also depends on the direction of travel. This means that the momentum of an object can change if: the object speeds up or slows down.

## What factors affect falling objects?

The factors affecting the terminal velocity of an object include:its mass.its surface area.the acceleration due to gravity , g.

## Is momentum the same as inertia?

Inertia is generally described as an object’s resistance to motion, with momentum being the tendency of an object to continue moving. …

## Can momentum be lost as heat?

If the net force acting on an object is zero, then the linear momentum is constant. In an elastic collision (such as a superball hitting and rebounding from the ground), no kinetic energy is lost. … In an inelastic collision, some of the energy will be lost to heat or sound or light or some other energy.

## Do heavier objects fall faster?

Galileo discovered that objects that are more dense, or have more mass, fall at a faster rate than less dense objects, due to this air resistance. A feather and brick dropped together. Air resistance causes the feather to fall more slowly.

## Why do objects with different mass fall?

On earth, two objects of different masses fall at the same rate. However, in space, larger masses exert greater gravitational attraction than smaller masses. This seems inconsistent. … A stronger force is needed to accelerate it downward so that it keeps pace with the smaller mass as the two fall.

## Does Momentum have direction?

Momentum is a derived quantity, calculated by multiplying the mass, m (a scalar quantity), times velocity, v (a vector quantity). This means that the momentum has a direction and that direction is always the same direction as the velocity of an object’s motion.

## What is the difference between momentum and impulse?

Momentum is mass in motion, and any moving object can have momentum. An object’s change in momentum is equal to its impulse. Impulse is a quantity of force times the time interval. Impulse is not equal to momentum itself; rather, it’s the increase or decrease of an object’s momentum.

## What is the formula of change in momentum?

Strategy. As noted above, when mass is constant, the change in momentum is given by Δ p = mΔv = m ( v f − v i ) .

## Does momentum depend on acceleration?

Momentum change depends on velocity change and the velocity change is greatest in case B (as stated above). Observe that each of the collisions above involve the rebound of a ball off a wall. Observe that the greater the rebound effect, the greater the acceleration, momentum change, and impulse.

## Is momentum always conserved?

Collisions. In collisions between two isolated objects Newton’s third law implies that momentum is always conserved. … Thus the total momentum of the system just before the collision is the same as the total momentum just after the collision.

## On what factors does the momentum of an object depend?

Both mass and velocity Right Lines: Momentum, a quantity that’s a good measure of the motion of a body, depends on mass and on velocity.

## What is the difference between momentum and velocity?

As nouns the difference between velocity and momentum is that velocity is (physics) a vector quantity that denotes the rate of change of position with respect to time, or a speed with the directional component while momentum is (physics) (of a body in motion) the product of its mass and velocity.
