You increase your walking speed from 1ms to 3ms in a period of 1s what is your acceleration?

Acceleration is the change in velocity of a body over time.
This means that we can determine it quite simply by dividing the change in velocity by the change in time.
In your case, we have a change of velocity of 2m/s, and a change in time of 1s.
Acceleration = Change in Velocity/Change in Time
Acceleration = 2 m/s / 1s
Acceleration = 2m/s2

What types of change in motion causes acceleration?
Motion is the change of position over time. The rate of change of position is called or speed. Speed combined with its direction is called velocity. The rate of change of velocity is called acceleration. So, motion in which the speed or direction are changing is accelerated motion. The question uses the word cause, which may be confusing. Technically when a force is applied to a mass, there is acceleration. When there is acceleration the velocity changes. If the object was in motion to begin with, it would speed up or slow down or change direction. If the object was at rest, the force would have caused an increase in speed from zero, so it would start moving. Therefore if you think of a causal relationship, it would be more proper to say force causes acceleration, which IS a change in motion. For an example, an easy one is your bicycle. If you pedal, you are applying force. That force cause the bicycle's speed to increase ... acceleration ... and you are in motion. If you apply more force, you will go faster. If you apply the brakes, you will slow down which is also acceleration (because speed is changing). There is only one way to have motion without acceleration and that is to travel at a constant velocity ... constant speed in a straight line. In practice, there is no motion without acceleration for any period of time, because there is always some minute change in speed or direction.
3 ways to accelerate?
To change the acceleration of a car: speed up, slow down or turn. Acceleration is any change in velocity. Velocity is "how fast" and in "what direction". To speed up is to accelerate (increase the velocity). To slow down is to deaccelerate (decrease the velocity) To turn is also a form of acceleration (changes the direction of the velocity).
What is the rate at which speed or direction changes?
Acceleration
What is the speed over a period of time?
Average speed = distance covered / time taken > SI units: metres per second (m/s)
A change in speed or direction?
A change in speed or direction is caused by a force and is called acceleration.
What is increase in speed?
acceleration
Definition of acceleration?
increase rate in speed of acceleration
Will acceleration only speed up an object?
In popular usage, "acceleration" means an increase in speed. In physics, any change in velocity is called an "acceleration".In popular usage, "acceleration" means an increase in speed.

In physics, any change in velocity is called an "acceleration".In popular usage, "acceleration" means an increase in speed. In physics, any change in velocity is called an "acceleration".
When a body undergoes an acceleration does its speed increase or decrease?
Both. Acceleration is a change in speed.
What is an increase in speed callled?
acceleration
An increase in speed is sometimes called?
acceleration
What has to happen to a car's acceleration and velocity for a car's speed to increase and have a positive acceleration?
The velocity has to increase in a positive direction. The increase in velocity in a positive direction is a positive acceleration.
When acceleration and velocity are in the same direction the speed will?
In that case, the speed will increase.
Can acceleration change with out increase or decrease speed?
yes the 3 types of acceleration are increased speed decrease speed or change in direction.
How are velocity and acceleration different?
acceleration is the increase of speed in a moving object. velocity is the speed and direction of a moving object.
If a ball rolls down a hill does its speed or acceleration increase?
If you roll a ball up a hill it undergoes negative upward and positive downward acceleration.
How can you increase or decrease acceleration?
acceleration is a change in speed or direction, so to answer your ? you slow down, speed up or make a turn :]
