# Describe the two ways in which velocity can change?

Velocity is the change of distance over change in time. Changing velocity involves acceleration. Acceleration is dependent upon the variables of force and mass.

### How do you calculate change in velocity?

Two ways: If the change in velocity is the result of hitting something, use the Momentum Equation. If the change in velocity is the result of applying a force, use the Impulse Equation. You probably mean this equation, which is: FT = m(Vf - Vo) Or, An object of mass "m" will change from velocity "Vo" to velocity "Vf" if the force "F" is applied for "T" seconds.

### It is the rate of change in speed with respect time?

Velocity??? Are you mad?? The answer is "Acceleration" as explained below. Velocity is not related to "rate of change", but its the speed in a specific direction, its a vector quantity!! The closest answer would be "Acceleration". According to Wikipedia, "acceleration is the change in velocity over time.[1] Because velocity is a vector, it can change in two ways: a change in magnitude and/or a change in direction. In one dimension, acceleration is the rate…

### Does speed change with velocity?

If the velocity changes, the speed may, or may not, change. The velocity can be thought of as having two components: a speed, and a direction. It is possible to change only the direction, for example, when an object moves in a circle at a constant speed. In this case, the velocity changes, but the speed does not.

### Why does velocity stay constant with decreasing momentum?

As far as we can tell, it doesn't. Momentum is defined as (mass) times (velocity). There appear to be only two ways in which momentum can decrease: either the mass has to magically evaporate, or else the velocity has to decrease. Since mass conservation is a nearly fundamental law of nature, that leaves us with velocity as the only way to change the momentum of a moving body.

### What are two ways to increase impulse?

By increase the objects mass and its velocity, Since Impusle (F x t) is the change in momentum and momentum is (Mass x Velocity) Impulse depends on the magnitude of the applied external force and the time that the force acts on the system. By increasing either of those, impulse on a system will be increased, and the system's momentum will change accordingly.

### What is the inertia of motion?

Inertia of motion is the resistance mass has to motion. It also is the resistance in change in momentum. Momentum includes two things: velocity and direction. When an object changes its velocity, the momentum of the object resists the change. Also, when an object does change its velocity, its momentum is directly changed. In general, the inertia of motion is matter's unwillingness to change velocity or momentum.
