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=20ss=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

What is needed to calculate kinetic energy?
Mass of a body and its speed are needed to calculate kinetic energy. Kinetic energy of an object = mv2/2 This formula is useful only when object's speed is much less than speed of light.
How can the average speed of an object be used to determine an unmeasured distance?
The average speed of an object can be used to determine an unmeasured distance by using the formula distance = speed x time. The time should also be known for this formula to work.
If speed is tripled then its kinetic energy of a mass is?
The formula for Kinetic Energy of an object is mv2/2 where m: mass of object and v:velocity of object Therefore when the speed of an object is tripled, then its kinetic energy becomes 9 times
What is the kinectic energy formula?
Kinetic energy of an object can be expressed by multiplying one half (0.5) against the object's mass, times the squared ^2 speed (or inertia) of the object.
How do you calculate the distance and object has traveled?
One formula that is often used is: distance = speed x time
What is needed to calculate kinetic energy?
Mass of a body and its speed are needed to calculate kinetic energy. Kinetic energy of an object = mv2/2 This formula is useful only when object's speed is much less than speed of light.
What is the formula for finding the speed of an object?
Speed = (distance traveled) divided by (time for that distance)
How do you determine the speed of a moving object?
The average speed of an moving object is determined by using the formula velocity=distance/time or v=d/t.
What is the average speed formula?
To know the speed of an object you have to know the distance travelled and the time it took to travel that distance
How can the average speed of an object be used to determine an unmeasured distance?
The average speed of an object can be used to determine an unmeasured distance by using the formula distance = speed x time. The time should also be known for this formula to work.
If speed is tripled then its kinetic energy of a mass is?
The formula for Kinetic Energy of an object is mv2/2 where m: mass of object and v:velocity of object Therefore when the speed of an object is tripled, then its kinetic energy becomes 9 times
What is the formula for constant speed?
§Constant speed means that the speed of the object under consideration is not changing, the direction of movement may or may not change.
Is there a formula for calculating the speed of an object based on the relative size of that object at different points in a known time frame?
No there is not i hope that helps!
What is a the formula for the speed of an object?
Distance traveled divided by time taken. (s=d/t)
What is the formula used to find distance?
The distance travelled by an object in a given time is given by:Distance = Speed * TimeAlternatively for an object that is accelerating:Distance = (Speed of object before acceleration is applied * Time) + (0.5 * Acceleration * Time squared)If the object is accelerating from speed zero, the first set of brackets is irrelevant.Also, if the object is falling to the ground, acceleration = 9.81
What is the kinectic energy formula?
Kinetic energy of an object can be expressed by multiplying one half (0.5) against the object's mass, times the squared ^2 speed (or inertia) of the object.
