Acceleration = final velocity (v)- starting velocity (u) divided by time a=(v-u)/t example: a car starts from rest and accelerates to 50 m/s in 10 seconds. u=0 m/s v=50m/s t=10s => a=(v-u)/t => a=(50-0)/10 a=5m/s² Be careful with the units: Time should be expressed in seconds, and all velocities in metres per second. As a result, acceleration is expresses as metres per second per second, or metres per second squared. Hope this helps!

∙ 13y agoAcceleration can be calculated many ways, like:
a= Δv/ Δt
acceleration is the change of velocity over the change of time, in other words, the rate at which velocity changes with respect to time.
If you run for 5s, starting at rest and reach 10m/s then
(10m/s - 0m/s)/(5s-0s) = 2m/s2
you are accelerating at 2m/s2.
f=ma
a=f/m
acceleration is the force applied divided by the mass of object experiencing force. If you push on an 2kg object with 6N of force then
6N/2kg = 3m/s2
the object is accelerating at 3m/s2

∙ 8y agoIf acceleration is constant over a period of time, then it is calculated as the change in velocity per unit time. If A is the acceleration over time T, U and V are the initial and final velocities respectively, thenA = (V - U)/T
If acceleration is not constant, then it is the derivative of the velocity with respect to time.

What is the force of an object with a mass of 65 kg and an an unknown acceleration?
Force is calculated by Newton's second law, F=ma. So the Force is the acceleration of the object multiplied by the mass. In this case you need an acceleration to find the answer. If, say you wanted the force that gravity has on the object, it would be F=mass*acceleration due to gravity. Here, F=65kg*9.81m/s= 637 Newtons
What is the value of acceleration for a body?
Acceleration means how fast the body's velocity changes - in symbols, dv/dt. Average acceleration during a certain time is equal to (change in velocity) / (time elapsed). Since you are dividing a velocity by a time, the standard unit for acceleration is (meters / second) / second, but this is normally written as meters / second squared.
What is the formula for acceleration?
a=dv/dt. By definition, acceleration is the rate of change of velocity. In mathematical notation, it is given as the formula stated above. Two special cases: 1. When acceleration is constant: The rate of change is a constant. Therefore, it can be calculated by: a=(vf - vi) / t where a is acceleration vf is final velocity vi is initial velocity and t is time taken 2. When velocity is constant: Velocity is not changing. The rate of change of velocity is zero. Acceleration has to be zero. * * * * * Note that velocity and acceleration are both VECTORS. Therefore, an object going round in a circle, at CONSTANT speed, has velocity and acceleration that are changing all the time - because the direction of motion is changing.
What happens if an unbalanced force applied to an object doubles?
The acceleration, from the Newton's law, can be calculated as:a0 = F0/mwhere F0 is the unbalanced force, m is the mass of the object.This is a linear equation, so if you double the force by 2, the acceleration will double as well:a1 = 2F0/m = 2(F0/m) = 2a0
What causes an object's velocity to change?
A change in velocity is caused by a change in acceleration. Objects do not speed up, slow down, or change direction unless they are pushed in some way. The acceleration (a) of an object with mass (m) produced by a given force (F) may be calculated using the equation a = F/m.
What is the acceleration?
Acceleration is the change in velocity with time, for linear (constant) acceleration it is calculated by: (End Speed -Start Speed)/time taken
This is calculated by change in velocity over time?
Acceleration.
How is force calculated if you know the mass and acceleration?
F = ma
What is the accelerate?
Acceleration is the change in velocity with time, for linear (constant) acceleration it is calculated by: (End Speed -Start Speed)/time taken
What can be calculated by dividing the force exerted on the object by the mass of the object?
That's the object's acceleration.
Why does second sq occurs in the unit of acceleration?
That's because you are dividing a speed by a time. In the case of constant acceleration, acceleration can be calculated as (difference in velocity) / time. In fact, that's basically how acceleration is defined. The corresponding units are (meters / second) / second.
Why does gravity change velocity?
Gravity exerts a force on objects; such a force (if not counteracted by some other force) will cause an acceleration, according to Newton's Second Law. The amount of the acceleration can be calculated as a = F/m.
Is gravity the same as weight?
Gravity is not the same as weight. Using the MKS unit system, gravity is a constant of acceleration (9.8m/s2) while weight is a Force in Newtons which can be calculated using: Fweight = mass*acceleration where mass is in kilograms and acceleration is the acceleration due to gravity.
How can use force in a scientific sentence?
An object's force is calculated by multiplying an object's mass by its acceleration

Does a gas balloon accelerate?
When a balloon ascends, it undergoes acceleration. This is in spite of the forces like gravity that acts on it. The acceleration of the balloon can be calculated using Newton's second law of physics.
What is the intensity sound of a space rocket?
The intensity sound of a space rocket is calculated based on its acceleration and height.
