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 has to happen to a car's acceleration and velocity for a car's speed to increase and have a positive acceleration?
The velocity has to increase in a positive direction. The increase in velocity in a positive direction is a positive acceleration.
What is positive and negative acceleration?
Positive acceleration = speeding up. Negative acceleration = slowing down.
Is increasing acceleration the same as positive acceleration?
No. "Positive acceleration" means increasing speed. The acceleration is usually constantin typical Physics examples and applications.
What is positive acceleration negative acceleration?
Positive is speeding up and negative is slowing down
What can positive acceleration called?
Positive acceleration could be called "speeding up" if you felt like it.
How is a negative acceleration different from a positive acceleration?
Actually, it depends on how you define the coordinate axes, but usually when moving forward, negative acceleration decreasesspeed, positive acceleration increasesit.
If objects get faster with time the direction of the acceleration is?
The acceleration is positive.
What is negative and acceleration?
Positive acceleration = speeding up. Negative acceleration = slowing down.
Both speed and acceleration include the direction of an objects motion?
Yes! In most problems direction needs to be defined as either positive or negative.
What is the value of acceleration of an object in freefall?
If the object is falling close to earth the acceleration would be 9.81m/s^2. Be sure to define direction as positive or negative in the problem! (When I do problems I like to define the down direction as positive so I don't have to deal with too many negatives)
Difference between negative and positive acceration?
Positive acceleration ==> speeding up Negative acceleration ==> slowing down
