Speed is the rate of change of position per unit time. The dimension is Length / Time. Common units are meters per second, miles per hour, feet per second. Velocity is nearly the same (same dimensions), except that velocity is a vector, meaning that it has direction as well.
Now acceleration is the rate of change of velocity. It also is a vector. Its dimensions are Length/(time^2). Typical units are meters/sec^2 and feet/sec^2.
What else can I help you with?
Are speed and acceleration the same?
No. Speed is the magnitude of velocity and acceleration is the change of velocity in time.
What kind of speed has no acceleration?
A constant speed has no acceleration. When an object is moving at a constant speed, its velocity remains the same over time, and there is no change in acceleration.
Why is the velocity 0 when your speed is constant?
It's not. If you speed is constant (but not zero), then your velocity won't be zero, either.You may be confusing this with the following: If your VELOCITY (not your speed) is constant, then your ACCELERATION is zero. Acceleration refers to how quickly velocity changes, so if velocity doesn't change at all, acceleration is zero.
What is difference between an object moving with uniform acceleration and an object moving with a constant velocity?
A motion with a constant speed will always be moving the same speed A motion with a constant acceleration will constantly be gaining speed, and does not remain moving at the same speed.
What has to happen to a car's acceleration and velocity for a car's speed to increase and have a positive acceleration?
For a car's speed to increase and have a positive acceleration, the car's velocity needs to be increasing in the same direction as its acceleration. This means that the car is speeding up. When the velocity and acceleration have the same sign (both positive or both negative), the car's speed will increase.
When acceleration and velocity are in the same direction the speed will?
In that case, the speed will increase.
What moving object speed up in what direct is the acceleration?
The acceleration is the same direction of the velocity
What is acceleration speed and velocity?
Speed is (distance covered) divided by (time taken to cover the distance).Velocity is a speed and its direction.Acceleration is any change of velocity.
If two automobiles have the same acceleration do they have the same velocity?
No. V=v0 +at is the formula for velocity, the acceleration 'a' can be the same but the initial velocity v0 may be different. If v0 is the same for the two automobiles , the velocity would be the same.
What is one similarity to speed velocity acceleration?
Speed, velocity, and acceleration all have momentum.
How does the direction of acceleration affect the directions of motion?
The direction of acceleration affects the direction of motion by causing a change in velocity. If the acceleration is in the same direction as the velocity, the speed of the object increases. If the acceleration is opposite to the velocity, the speed decreases, and if the acceleration is perpendicular to the velocity, the object changes direction without changing speed.
How are speed velocity and acceleration are the same?
They all have to do with how fast an object is moving
