What else can I help you with?
What is the term that describes a decrease in acceleration?
it is still acceleration, but it is negative.
When is the term negative acceleration used?
The term negative acceleration is used when something is slowing down from its motion. When pushing the brakes the car will negatively acceleration to slow down .
What term refers to any change in velocity?
Acceleration is the term that refers to any change in velocity. It can either be a speeding up (positive acceleration) or a slowing down (negative acceleration) of an object.
Is the negative acceleration the same as deceleration?
Yes no doubt. It is a short term.
What term is used to denote the change of velocity with time?
Acceleration is the term used to denote the change of velocity with time. It can be in the form of either speeding up (positive acceleration) or slowing down (negative acceleration).
Can acceleration be a negative number?
Yes, the scalar value of acceleration can be a negative number. Acceleration is the rate of change of velocity. If the speed of an object is reducing (it is slowing down), then the object is subject to a negative acceleration. An example is when you apply the brakes in a car. The brakes change the speed of the car from a higher value to a lower value, thus imposing a negative acceleration. Colloquially, people speak of deceleration, however the correct term is negative acceleration.
Can a car have negative velocity and negative acceleration?
It cannot have negative velocity, it can have negative acceleration.
Can there be a positive acceleration and a negative acceleration?
Yes, acceleration can be positive and negative because acceleration is a vector. It has both direction and magnitude. The direction is what makes it positive or negative. Negative acceleration is usually called deceleration.
What is negative and acceleration?
Positive acceleration = speeding up. Negative acceleration = slowing down.
Is it true that a negative acceleration always means that a moving object is decelerating?
Yes. That is what the term deceleration means.
Which term explains whether an object's velocity has increased and decreased over time?
Acceleration is the term that explains whether an object's velocity has increased or decreased over time. Positive acceleration indicates velocity is increasing, while negative acceleration indicates velocity is decreasing.
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.
