# The Change in velocity and direction.

• Gprime
In summary, "change in velocity and direction" refers to the alteration in both the speed and direction of an object's motion and can be caused by various factors such as forces, collisions, and interactions with a gravitational field. It is measured using mathematical formulas and physical quantities and can impact an object's motion by causing it to speed up, slow down, change direction, or come to a stop. The difference between uniform and non-uniform change lies in the object's constant or changing velocity and direction.

## Homework Statement

What is the acceleration of a bullet that was shot at 40.m/s in the horizontal and then changed to a velocity of 44.5m/s at 26.1* below the horizontal in a time of 2.0 seconds.

## Homework Equations

vf-vi= delta v a= delta v / time

## The Attempt at a Solution

I have tried to solve using head to tail diagram and i ended up 41m/s2. I am not entirely sure of this answer, and I have a test next morning on this.

That's not correct. Show how you got that result.

## 1. What is meant by "change in velocity and direction"?

The term "change in velocity and direction" refers to the alteration in both the speed and direction of an object's motion. It can occur when an object speeds up, slows down, or changes its course.

## 2. What causes a change in velocity and direction?

A change in velocity and direction can be caused by various factors such as forces acting on the object, collisions with other objects, or interactions with a gravitational field. Inertia and momentum also play a role in determining the change in an object's velocity and direction.

## 3. How is the change in velocity and direction measured?

The change in velocity and direction is measured using mathematical formulas and physical quantities such as acceleration, displacement, and time. These quantities are used to calculate the change in an object's speed and direction over a specific period of time.

## 4. What is the difference between uniform and non-uniform change in velocity and direction?

In uniform change, the object's velocity and direction remain constant, meaning there is no acceleration or change in its motion. In contrast, non-uniform change involves an alteration in the object's velocity and direction, indicating a change in its motion.

## 5. How does the change in velocity and direction impact an object's motion?

A change in velocity and direction can affect an object's motion in different ways. It can cause the object to speed up or slow down, change its direction of motion, or even come to a complete stop. It is also essential to consider the object's mass and the magnitude of the change in velocity and direction to determine its impact on the overall motion.
