What else can I help you with?
Can the speed of the particle ever be negative if so give an example if not explian why?
see speed cannot de negative se speed = distance / time and neithr distance nor time can be negative they r always positive so speed cannot be negative but velocity can be negative
If your speed changes from 10 kmh to 6 kmh you have a(n) acceleration. positive or negtive?
if your speed is in the positive direction you are slowing down and acceleration is the opposite direction and is negative acceleration.However if your speed is the negative direction ( like running backwards) and you slow down then acceleration is in the opposite direction and positive.In your case if speed is 10 kmh positive going to 6kmh then acceleration is negative
Where could you find negative numbers?
If an altitude above sea level is positive, then an altitude below sea level is negative.If having money is positive, having a debt is negative.If gaining money is positive, losing money is negative (a negative gain).If an increase in speed is a positive acceleration, a decrease in speed is a negative acceleration.Any other similar case, where you define one thing as positive, and its opposite as negative.
Can a speed of a body be negative?
The 'speed' of a body cannot be negative. But if you are stating the 'velocity' then it can be negative. Negative velocity means it is going opposite to the direction that you decided to call the positive direction.
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.
Can instantaneous speed be negative?
Velocity refers to the rate of change in distance of an object, and also the direction of the change, where speed just refers to the rate of change without regard to the direction, so if the object moved at all, it would have an average speed greater than zero, so No.
Does acceleration have a negative or positive value if the velocity is increasing speed?
In this case, acceleration is positive. Negative acceleration would cause the object to slow down (decelerate.)
Describing what is feedback system and differentiating between positive and negative feedback?
when a woman's contractions speed up during labor is negative or positive feedback
Why can velocity be negative but nonzero speed is always positive?
Velocity includes both speed and direction, so a negative velocity indicates motion in the opposite direction. Speed, on the other hand, is a scalar quantity representing the magnitude of velocity without regard to direction, and therefore is always positive.
What is the difference between positive and negative momentum?
The difference between positive and negative momentum is the direction that the object is going. Left and down are negative, right and up are positive. For example: if a ball is rolling to the left, it has a negative momentum.
Is it possible to have negative value in speed and displacement?
No, in physics, speed and displacement are scalar quantities that represent magnitudes and cannot be negative. However, the direction of motion can be indicated by assigning a negative or positive sign to the speed or displacement value.
What kind of slope does acceleration have?
Acceleration is a vector quantity and can have positive, negative, or zero slope. A positive slope indicates an increase in speed, a negative slope indicates a decrease in speed, and a zero slope indicates constant velocity.
