Accelaration is defined as change in velocity divide by what?

Wiki User

Divided by time.Average acceleration is (change in velocity) / (time interval)

Instantaneous acceleration is calculated by making the time interval very small. This is written as dv/dt.

What is acceleration multiplied by time?

Since acceleration is defined as change of velocity divide by time, it has units of (velocity / time). acceleration x time = (velocity / time) x time = velocity

Acceleration is defined as a change in velocity over time. if a runner increases velocity from 2 ms to 4 ma over a period of 20 seconds what is her acceleration?

The idea is that you should: a) Calculate the change in velocity. b) Divide this change by the time. This gives you the average acceleration over the 20 seconds, in this case.

When calculating acceleration to find the change in velocity you subtract the what velocity from the final velocity?

You subtract the initial velocity from the final velocity and divide by the time interval.

How average acceleration is found?

You divide a change in velocity by the time it takes for that change.

How do you find vertical acceleration?

You divide the change in vertical velocity by the time it takes for that change to occur.

What is the acceleration of a car that is travelingin a straight line at a constant speed?

You are supposed to divide the change in velocity, by the time. In this case, the change of velocity is zero. Divide that by any time, and you get zero.Answer 2The acceleration is zeroIf the speed and direction of an object is constant, then the acceleration is zero m/s2The acceleration is defined as the velocity change per time ratio.Accelerating means increasing speed. The only way one can accelerate and travel at a constant speed is when he is changing his direction, that is, moving in a circle. This is because acceleration is the rate of change of velocity. Velocity means speed with a direction. So if the speed is kept constant, the direction has to change for acceleration.Refer to link below for more information and for more examples.

Which explains how to calculate the average acceleration of a moving object?

Just divide the change in velocity, by the time it takes to carry out this change.

The impulse given to a ball with mass of 4 kg is 16 Nsec If the ball starts from rest what is its final velocity?

An impulse is simply a change of momentum, and momentum is defined as mass x velocity; so you just divide the momentum by the mass to get the velocity. Note about the units: newton x second is the same as kilogram x meter/second2.

What is the relationship between velocity and time?

Velocity is a vector, which means it has magnitude and direction. Velocity is defined as the rate of change of displacement (distance), or delta-s over delta-t. In other words, if you divide the distance traveled by the time it took to cover the distance, you know the velocity. For example, if you cover 100 miles (delta-s = 100 miles) in two hours (delta-t = 2 hours), then the velocity is 100/2 = 50 miles per hour. Note that a change in direction also constitutes a change in velocity. But this example concentrates on the magnitude, that is, speed.

What is the expression for average acceleration?

Acceleration = Change in velocity divided by the change in time. This formula only works if velocity is constant. If velocity is not constant, find the acceleration for both points in time. Then add the two accelerations and divide by 2.

Acceleration is rate of change ofTIME?

Acceleration is the rate of change of velocity, with respect to time. In symbols, a = dv/dt. That simply means that you divide change of velocity by change of time, for a fairly small amount of time (the smaller, the more accurate).

What should you do if you want calculate acceleration of a car?

You should divide the change in velocity of the car by the time interval.

How to find acceleration without using force?

You can use the basic definition of acceleration, as a change of speed. In other words, measure the velocity at some moment, and at a later moment. Then divide the change of velocity by the time.

What is momentum divided by velocity?

Momentum = mass x velocity. If you divide out the velocity you get mass.

Are velocity and acceleration the same?

They are definitely NOT the same. Acceleration is not velocity; acceleration is the RATE OF CHANGE of velocity. In symbols: a = dv/dt, which basically means that you divide the difference of velocity by the time, for a small time interval. Acceleration and velocity are both vectors.

What is acceleration and velocity?

Acceleration and velocityVelocity - which is not quite the same thing as speed -- is the measure of the rate of change in position. In other words, to calculate velocity, we divide the change in an object's displacement -- how far it moved -- by the time it took to move. If an object moves, say, 100 feet in 10 seconds, its velocity is 100/10 = 10 feet per second (ft/s). Acceleration is the rate of change of velocity. If an object increases its speed from, say, 10 ft/s to 60 ft/s in five seconds, its acceleration is 10 feet per second per second, or 10 feet per second squared (ft/s2).How did we arrive at that figure? Divide the change in velocity by the change in time. The change in velocity is 60 - 10 = 50 ft/s. The change in time is 5 - 0 = 5 s. Hence, 50/5 = 10 ft/s2.

What is the acceleration of an object?

That's the rate of change of its velocity - how fast its velocity changes. In symbols: a = dv/dt. In the SI, a speed, as well as a velocity, are expressed in meters/second; thus, the natural unit for acceleration is (meters/second)/second, usually written as meters / second squared - since you need to divide a velocity (more precisely, a change of velocity) by a time. Note that since velocity is a vector, so is acceleration.

Why is average speed distance divided by time but average velocity is initial velocity plus final velocity divided by 2?

Because velocity is a measurement of change of speed rather than an average constant speed. To get the average speed (as you rightly said) - you divide the total distance travelled by the time taken. The average velocity is the change in speed over time (either an increase or decrease).

How do you find acceleration due to a driving mass?

Acceleration is the change in velocity over time. Acceleration = change in velocity / time elapsed So, find the initial velocity of the mass (0 if starting from rest) and another velocity that occurs afterwards and find the difference. Then, divide the change in velocity by the time elapsed. If you know the mass of and the force acting on the object, you can use this formula: Force = mass x acceleration Substitute for your known variables and solve algebraically.

How do you find Mass using Momentum and velocity?

Momentum = (mass) x (velocity)Divide each side of the equation by (velocity) :(mass) = Momentum/(velocity)
