# Speed Velocity and Acceleration Problems in Physics

Speed:

Objects travel a certain distance in a given time frame and this is called their speed.

Formula:

### Define Velocity:

Basically, velocity is just how fast a person’s displacement changes.

Formula:

### which explains the information needed to calculate speed and velocity in Physics?

Distance covered and time taken are required to calculate speed.

it is denoted by v and its formula is:

v\;=\;\frac st

Where S is Distance and t is time in Formula

It is necessary to take time into consideration when calculating the velocity of the moving body.

it is also denoted by v and its formula is:
v\;=\;\frac dt

### when is the average velocity of an object equal to the instantaneous velocity?

The average velocity of an object is equal to its instantaneous velocity if its acceleration is zero. There cannot be any change in speed or direction of an object if its acceleration is zero. It follows that if an object is moving in the same direction or at zero acceleration, its speed or direction can’t change.

### which pair of sentences is describing the same velocity?

Vehicles moving in opposite directions have the same velocity.

Essentially, acceleration is the rate at which velocity changes, while velocity is the rate at which position changes. Thus, velocity, acceleration, and position are connected.
