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.
How would you define acceleration due to gravity?
That means that the acceleration of an object is caused by the force of gravity acting on the object.
When can you used the positive acceleration due to gravity and negative acceleration due to gravity?
If you define the "up" direction as "positive", then the acceleration is negative, because it is downward. If you define "down" as positive, then acceleration is negative. You can use any convention; just be sure to be consistent within a particular calculation, to avoid errors.
Can a car driving backwards have a positive acceleration?
Yes, it just depends on how you define which way is "positive". If you define the "backwards" direction to be the positive direction, acceleration will be positive when going "backwards". Note that if we define the axes like this, going "forwards" will give the car a negative acceleration.
What is the define for acceleration?
rate at which a rate changes a= change in velocity divided by time

How can you define acceleration due to gravity?
yes, 9.81 m/s^2
What is the define for acceleration?
rate at which a rate changes a= change in velocity divided by time
Define angular impulse?
Angular impulse is defined as the rate-of-change of the angular acceleration.
How do you get initial velocity without acceleration?
Define a moving coordinate system with respect to a stationary object.
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)
Define Change in speed?
change in speed is acceleration. change in speed is the slope of the speed versus time graph, or the derivative of such.
Why is defining only force not enough?
If you are talking about problems involving Newton's second law of motion, F = ma, you would need to define two of the three variables of force, mass, and acceleration in order to find the third variable. If you have force and mass, you can find acceleration. If you have force and acceleration, you can find mass. If you have mass and acceleration you can find force.
Is mass times acceleration a force?
Yes, according to Newton's Second Law, F = ma. This means that for more mass, you need more force to get the same acceleration; also that, with more force, there will be more acceleration. This can be used to define the unit of force, as it is actually done in the SI: Force (in Newton) = (mass) (acceleration) = kg. x m / sec^2.
