Want this question answered?
it is still acceleration, but it is negative.
acceleration is a change in speed or direction, so to answer your ? you slow down, speed up or make a turn :]
acceleration
No, in basic physics acceleration depends on Newton's Second Law Net Force equals mass times acceleration
By F = ma, if the force remains constant, and the mass decreases, this would mean that the acceleration has increased by exactly the same factor as the decrease in mass. That is, if the mass of a substance was halved, its acceleration would have doubled exactly.
it is still acceleration, but it is negative.
Decrease.
yes the 3 types of acceleration are increased speed decrease speed or change in direction.
If net force acting on a mass decreases, the acceleration of the object decreases. But if the mass of an object were to decrease while a constant net force acted on it, its acceleration would INcrease. If the net force on the object AND the object's mass both decrease, the object's acceleration could either increase OR decrease. We'd need the actual numbers in order to calculate how it would turn out.
Deceleration or negative acceleration.
Both. Acceleration is a change in speed.
Negative acceleration, or deceleration.
retardation is nothing but the decrease in speed. so if the increase in speed can be taken as positive then for sure decrease in speed can be taken as negative acceleration.
One could find reviews on baby sleds on the Internet. On your Search bar, enter "Baby Sled Reviews" and it will bring up various companies that manufacture baby sleds.
Any change of velocity, including a decrease of speed, is described and measured as acceleration. Assuming the velocity and acceleration vectors point in the same direction, then in the case of decreasing speed, the magnitude of the acceleration is a negative value. Negative acceleration is often called deceleration, but that is just a special case of acceleration.
Acceleration and deceleration are related by their their sign. Acceleration is positive ( increase in velocity with time) and deceleration is negative (decrease in velocity with time).
Well, the more the air resistance, the lower the acceleration.
