## What happens to velocity and acceleration when speed increases?

Explanation: **Speed increases when velocity and acceleration have the same sign**. In section A, the velocity is positive because it’s above the x axis and the slope is positive, meaning that the acceleration is positive.

## What happens to velocity when you accelerate?

The **velocity is changing over the course** of time. In fact, the velocity is changing by a constant amount – 10 m/s – in each second of time. Anytime an object’s velocity is changing, the object is said to be accelerating; it has an acceleration.

## What is the relationship between speed velocity and acceleration?

Speed is the rate of change of distance(basically how much distance(m) has been covered in a particular time(s)). Velocity is the rate of change of displacement( change of distance in a particular direction with respect to time) , and acceleration is **the rate of change of velocity per unit of time**.

## Does speed increase when velocity increases?

Velocity has a magnitude and a direction. Speed has the same value and units as velocity; speed is a number. Speed is **increasing when the velocity and acceleration have the same** sign.

## When speed increases does acceleration increase?

Any change in the velocity of an object results in an acceleration: increasing speed (what people usually mean when they say acceleration), decreasing speed (also called deceleration or retardation ), or changing direction (called centripetal acceleration ).

## What is velocity and acceleration and speed?

Speed, velocity and acceleration**Average speed is distance divided by time.** **Velocity is speed in a given direction.** **Acceleration is change in velocity divided by time**. Movement can be shown in distance-time and velocity-time graphs.

## What is acceleration and velocity?

Velocity is the rate of change of displacement. **Acceleration is the rate of change of velocity**. Velocity is a vector quantity because it consists of both magnitude and direction. Acceleration is also a vector quantity as it is just the rate of change of velocity.

## Are velocity and acceleration directly proportional?

Velocity is **directly proportional to time when acceleration is constant** (v ∝ t).

## Which of the cars is accelerating?

By 60 mph (97 km/h) acceleration time (3.0 seconds or less)
