What else can I help you with?
When you press your bicycle's brakeswhat happens to your speedvelocityand acceleration?
your seed,velocity,and acceleration will be slow When you brake, your acceleration increases (!), your velocity decreases (and in this case, there is no difference between velocity and speed). Negative acceleration increases when braking a moving bike.
Differentiate positive acceleration and negative acceleration?
A positive acceleration is a change in velocity such that the latter velocity is greater than the former velocity and is therefore going fasterwhile a negative acceleration or deceleration is a change in velocity such that the latter velocity is lesser than the former velocity and is therefore going slower.Now let us look at the equation of a uniform acceleration (the change in velocity is uniform):a = (vf-vi)/sIf the final velocity is greater, you will have a positive acceleration. If the initial velocity is greater, you will have a deceleration.
When velocity is zero and acceleration is negative what happens to an object's motion?
When velocity is zero and acceleration is negative, the object may be coming to a stop and starting to move in the opposite direction. The negative acceleration is causing the object to slow down, while the zero velocity indicates that it has momentarily come to a halt before changing direction.
When a car's velocity is positive and it's acceleration is negative what is happening to the car motion?
The car is slowing down
Does an object that is moving in a linear path with an acceleration in the direction opposite to the motion have a decreasing velocity?
No. Acceleration is Delta-Velocity / Delta-Time. If Acceleration is negative then that means that either Delta Velocity is negative or Delta Time is negative---which is not practical. For Acceleartion to be negative, that means the Velocity has to Decrease. (where Delta Velocity is change in Velocity or V2 - V1)
When velocity is negative and acceleration is positive what happens to an objects motion?
Its slowing down (but still moving).

How is motion demonstratd with snowboarding?
Snowboarding demonstrates speed, velocity, and acceleration. It can also demonstrate a positive or negative value for velocity and acceleration.

What is the motion of an object with negative acceleration?
An object with negative acceleration is slowing down. Negative acceleration means that the velocity of the object is decreasing over time, causing it to decelerate or come to a stop.
When is acceleration neg?
Acceleration is negative if velocity is decreasing with time. Since velocity is a vector this can occur in one of two ways: 1) you are slowing down in the direction of motion and the velocity in that direction is defined as positive (this is what we usually mean by negative acceleration) 2) you are speeding up in the direction of motion and the velocity in that direction is defined as negative. An example of this is an object launched into the air which immediately starts to decelerate in it's upward velocity, reaches it's highest velocity, and then begins accelerating towards the ground. If we call the velocity upward a positive velocity, then when it starts falling, it has negative velocity. Note that acceleration (due to gravity) is negative the whole time.
When angular velocity decreases the direction of angular acceleration is opposite to angular velocity .why?
Take the velocity to be in positive direction. Positive acceleration increases velocity and they are in the same direction. Negative acceleration reduce velocity and they are in opposite direction. It does not matter if the motion in linear or anfular.
How can you tell if acceleration is positive or negative?
Acceleration is positive when an object is speeding up in the positive direction (e.g., increasing velocity), and negative when the object is slowing down in the positive direction or moving in the negative direction (e.g., decreasing velocity). The sign of acceleration depends on the direction of the change in velocity relative to the direction of motion.
What would a negative acceleration tell you about the object in motion?
the car is at a constant speed---------------------------------------------------------I'm pretty sure that if the acceleration is negative, the car is slowing down. But if the velocity is negative, the car is either heading south or down (velocity refers to speed and direction.. according to my physics teacher).
