Magnitude of acceleration =
(change in speed) / (time for the change) =
(100 - 0)/10 = (10 km/hr-sec) x (1 hr/3,600 sec) = 0.00278 km/sec2 or 36,000 km/hr2 .

If a rock is dropped and it's speed increases from 0 to 4.9 in about 3 seconds. what is the acceleration?
Assuming that your units of velocity are in units/second Acceleration = (velocity 2 - velocity 1) / time Acceleration = (4.9 - 0) / 3 Acceleration =1.63 *With correct significant figures the answer is 2
An arrow in flight has an initial velocity of 65 meters per second and 10 seconds later it has a velocity of 35 meters per second Which is the acceleration of the arrow?
Acceleration of the arrow is -3m/s2A = (velocity minus initial velocity) / time
Why the second is squared in acceleration?
it is very simple........... velocity or speed = distance / time. acceleration = velocity / time but, we know that velocity = distance / time so just substitute the equation of velocity in acceleration...... so, finally we get , acceleration = distance/time*time so it is time squared.
How do you work out velocity when given acceleration and time?
Answer: v=u + at v (Velocity) = u (Starting velocity) + a (acceleration) x t (time) So, starting from stationary (u=0), the velocity is simply a x t e.g. if the acceleration is 5mph per second per second, after 10 seconds you would be travelling at 50mph. Answer: The above is for constant acceleration. In the case of variable acceleration, integration has to be used.
What is acceleration time graph?
The change in the velocity divided by time in meters per second squared.
What can Acceleration be defined as?
Velocity divided by time. The amount the the velocity increases by per second.

Acceleration is defined as a change in velocity over time . If a runner increases velocity from 2 ms to 4 ms over a period of of A seconds what is her acceleration?
It is 0.1 metre per second-squared.
What is her acceleration if 'acceleration is defined as a change in velocity over time. If a runner increases velocity from 2 ms to 4 ms over a period of 20 seconds?
It is 0.1 metre per second-squared.

When the body is drop how is velocity related to the time?
If air resistance is negligible, velocity increases at a rate of 9.8 meters / second every second, that is to say, the acceleration is 9.8 meters per second square.
How are veloc ty and acceleration related?
Acceleration is the rate of velocity incerease: > Acceleration = velocity increase / time > Units : metres per second increase per second
What is acceleration and its si unit?
Acceleration is the rate of change of velocity - how fast a velocity changes. Therefore, its units are naturally (meters/second) / second, usually written as meters/second2.Acceleration is the rate of change of velocity - how fast a velocity changes.

What is change in the velocity of a falling object?
Any change in the velocity of anything is known as 'acceleration'. In the case of a falling object near the Earth's surface, the direction of the velocity is constant, and its magnitude increases by 9.8 meters (32.2 feet) per second, every second.
What is the definition for the rate of motion?
The rate of change of motion is known as acceleration. Acceleration is the change in velocity over change in time. Velocity is the rate of change of position, or change in position over change in time.
What is simple acceleration?
It is the rate of change of velocity. If the velocity changes from five to six meters per second in one second, then the acceleration is one meter per second per second.
