Formula for speed of an object?

Answer 1

If an object is at rest then falls vertically you can use the formula Vsquared=Usquared+2AD (Sorry keyboard wont let me do the 2 for square)

Where V = Final Velocity (speed),

U=Initial velocity (at rest =0)

A= Acceleration (9.81 metres/sec or 32ft/sec in imperial)

S= Distance.

An object on a shelf 3m above the ground falls. Speed on impact with the floor would be

Square root V= 0 squared+2*9.81*3: = 7.672m/s
Speed = Distance/Time (Distance divided by Time)
Speed=distance/time
Speed is measured in m/s (meters per second)

You can calculate speed using the following formula :

Speed = Distance/Time

Examples:distance=100 meters=20s

s=d/t

s=100m/20s

s= 5m/s

the units for speed equal up to m/s units always.

so then your speed is 5 m/s

Answer 2

There are many answers for this:- However, the most basic answer:- speed = total distance travelled / time taken

Answer 3

It is:

Distance/Time=Speed

Distance, divided by time, equals speed

Answer 4

Newtons second law: f=mXa, or force equals mass times acceleration

Answer 5

The formula for speed is distance divided by time. It is typically represented as: speed = distance / time. Speed is a scalar quantity that measures how fast an object is moving.

Answer 6

Speed= distance travelled/time taken.
