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!

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


If the speeding train hits the brakes and it takes the train 39 seconds to go from 54.8 ms to 12 ms what is the acceleration?

Well, isn't that a happy little math problem we have here! To find the acceleration, we can use the formula: acceleration = (final velocity - initial velocity) / time. Plugging in the values, we get: acceleration = (12 - 54.8) / 39. So, the acceleration of the train is approximately -1.27 m/s². Remember, there are no mistakes in math, just happy little accidents!

What is the acceleration?

Acceleration is the rate at which an object changes its velocity. It can be calculated by dividing the change in velocity by the time taken for that change to occur. Acceleration can be in the same direction as the velocity (speeding up) or in the opposite direction (slowing down).
