Difference between negative and positive acceration?
Positive acceleration ==> speeding up Negative acceleration ==> slowing down
What is positive negative and zero acceleration is?
positive acceleration is when things speed up; negative acceleration is when things slow down; and zero acceleration is when things do not speed up or slow down, this is called constant speed, or no change in velocity.
When acceleration upward or downward direction is taken positivw or negative?
If it is gravitational acceleration then it it is positive in downward and negative in upward direction..if it is not gravitational acceleration then it is depending upon the value of acceleration.
What type of acceleration does a trapezium on a velocity time graph represents?
A period of constant positive acceleration;a second period of zero acceleration; a third period of constant negative acceleration.
What shall you do when you find the value of driving force is negative?
The acceleration is in the direction of the positive force so you will have deceleration in the direction of the negative force.
