Question

Answer the following.

what is speed?​

Answer 1

speed in every day use and in kinematics , the speed of an object in the magnitude of the change in the position , it is thus a scalar quality

Answer 2

Speed :-

Distance travelled by per unit time is called as speed.

• SI unit of speed is m/s

• Formula is speed = Distance travelled ÷ Time taken

• Speed is scalar quantity.

• Speedometer is used to measure the speed of a car.

More details :

Average Speed :-

The average speed of a body is the total distance travelled divided by the total time taken to cover the distance.

• Average speed = Total distance travelled ÷ Total time taken

Uniform speed :-

A body has a uniform speed if it travels equal distance in equal intervals of time,no matter how small these intervals may be.

Velocity :-

Displacement produced per unit time in a given direction.

• Velocity = Displacement ÷ Time taken

• SI unit of velocity is m/s

• Velocity is vector quantity.
