Acceleration is zero since 55 mph is velocity and it is constant. Acceleration is defined as the rate of change in velocity. The speed is the absolute value of velocity so it is also 55.

### What happens to your speed if you have a negative acceleration do you speed up or slow down?

If you have a negative acceleration, you are slowing down. Acceleration is the rate of change of speed, so a negative acceleration means a decrease in speed.

### If your speed slows down you will have what acceleration?

If your speed slows down, yYou will have negative acceleration or deceleration.

### What is the difference between speed and accelaration?

Speed is the rate at which an object moves, while acceleration is the rate at which the speed of an object changes. Speed is a scalar quantity (has magnitude only), while acceleration is a vector quantity (has magnitude and direction).

### What is positive negative and zero acceleration is?

positive acceleration is when things speed up; negative acceleration is when things slow down; and zero acceleration is when things do not speed up or slow down, this is called constant speed, or no change in velocity.

### Does the distance a toy car travels down a ramp affect its speed?

yes This is because of the fact that gravity is a measure of acceleration. The longer the car has to accelerate the faster is will be by the end.

### How can you identify how quickly speed is changing?

You can identify how quickly speed is changing by calculating acceleration, which is the rate of change of speed over time. Acceleration can be calculated using the formula: acceleration = (final speed - initial speed) / time. A positive acceleration indicates speeding up, while a negative acceleration indicates slowing down.

### What does decceleration mean?

Deceleration refers to a decrease in speed or a slowing down of motion. It is the opposite of acceleration, where an object is gaining speed.

### What is the acceleration of a car that is going at a steady speed of 60 mph?

The acceleration of a car moving at a steady speed of 60 mph is zero. Acceleration is the rate of change of velocity, and if the car is maintaining a constant speed, then there is no change in velocity, hence no acceleration.

### What is the difference between acceleration and deceleration?

Acceleration means speeding up or getting faster. Deceleration means losing speed or speed rate decreasing. 'Celer' is the Latin word for fast or speedy. - Answer Deceleration is the loss in speed or slowing down. Acceleration is the increase in speed.

### Why would highway workers be against rasing speed limits?

Well you see considering that highway workers work on the highway and if the speed limit was raised, then there's more of a possibility of a car "flying" down the highway and hitting the highway worker

### If your speed changes from 10 kmh to 6 kmh you have a(n) acceleration. positive or negtive?

if your speed is in the positive direction you are slowing down and acceleration is the opposite direction and is negative acceleration.However if your speed is the negative direction ( like running backwards) and you slow down then acceleration is in the opposite direction and positive.In your case if speed is 10 kmh positive going to 6kmh then acceleration is negative

### What is Acceleartion?

acceleration is changes in speed slowing down and speeding up.
