Acceleration is a change in velocity. Assuming a constant direction, if you're speeding up that is positive acceleration. If you are slowing down, that's negative acceleration. Either way you are accelerating.
changing direction, speeding up, and slowing down
car speeding up
If a car is speeding up, it's initial speed is LOWER than it's final speed.
The car's acceleration is in forward direction.
Speeding up.
No. Negative acceleration means that you are decreasing in acceleration, like braking a car. Therefore, you can't be speeding up because speed and acceleration are connected. You can't travel at a faster speed if you are braking.
speeding of car speeding of a free falling object.
false A car can have a negative acceleration and be speeding up. A negative acceleration determines the direction of the acceleration A car with forward acceleration will speed up in the forward direction A car moving forward with a negative acceleration will slow down A car not moving with a negative acceleration will speed up in the backward direction A car moving backward with a negative acceleration will speed up in the backward direction
the car could be traveling in a straight line and slowing down (negative acceleration), speeding up (positive acceleration) or maintaining constant speed (zero acceleration).
Positive acceleration = speeding up. Negative acceleration = slowing down.
Positive acceleration results in the object speeding up, such as a car going from 0mph to 30mph. Negative acceleration is the object decelerating, such as using the brake in a car.
Positive acceleration = speeding up. Negative acceleration = slowing down.
The process of speeding up
There is no acceleration. Because the car is in a straight line, it is moving neither to the left or to the right, making no acceleration. Because it is at a constant speed, not speeding up or slowing down, there is no acceleration there. Therefore, no acceleration
