Acceleration is change in velocity. It is a vector, so some direction is choosen as positive and the opposite direction as negative. Then you have two possibilities;(1) the object is increasing its speed in the negative direction. (2) the object is decreasing its speed in the positive direction. Both of these give negative acceleration. For example; if up is choosen as positive then acceleration due to gravity is always negative because when a projectile is projected up with some initial velocity it decreases its speed on the way up. But on the way down its increasing its speed, in the negative direction.
What else can I help you with?
What is a negative acceleration called?
You'll find a lot of people who call it "deceleration". But in real Physics, there's no such thing.There's only positive or negative acceleration, depending on whether the acceleration is inthe same or opposite direction compared to what you decided to call the positive direction.Negative acceleration is sometimes, but not always, associated with something that's slowing down.
What is the definition of accleration?
Acceleration is the rate of change of velocity over time. It can be positive (speeding up), negative (slowing down), or zero (constant velocity). Mathematically, acceleration is calculated as the change in velocity divided by the time interval over which the change occurs.
An object that is accelerating maybe slowing down or speeding up?
An object that is accelerating is either speeding up or slowing down. If the acceleration is in the same direction as the velocity, the object is speeding up. If the acceleration is opposite to the velocity, the object is slowing down.
When is the accleration of a body is positive?
The acceleration of a body is positive when the body is speeding up in the direction of its velocity. This occurs when the force applied to the body is in the same direction as its motion, causing it to accelerate positively.
A negative plus a negative equal?
A negative plus a negative equals a bigger negative number.
Disscuss the relationship between velocity and accleration?
accleration is the speed. Velocity is when you know the speed of an object and its direction.
Who are the founders of accleration due to gravity?
Mianus
What are units for accleration?
kg m/s2
What are two types of accleration?
Changes in speed or direction
Formula constant accleration?
Acceleration with respect to time = a , where 'a' is a constant.
What is acceleation?
if that is a typo and you mean accleration it means going fast
Could a bad ball joint cause vibration on accleration?
Yes
What will cause an engine to bog out on accleration?
clogged up catylatic converter.
Automatic or standard veichles have faster acceleration?
automatic has faster accleration
Is equivalent to an objects mass times accleration due to gravity?
Weight.
What equal accleration on a speed vs time graph?
The gradient of the graph.
The calculation of mass x accleration applies to which of newtons laws of motion?
the 2nd one
