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.
Why is retardation called negative acceleration?
retardation is nothing but the decrease in speed. so if the increase in speed can be taken as positive then for sure decrease in speed can be taken as negative 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 is positive acceleration negative acceleration?
Positive is speeding up and negative is slowing down
What is negative and acceleration?
Positive acceleration = speeding up. Negative acceleration = slowing down.
Difference between negative and positive acceration?
Positive acceleration ==> speeding up Negative acceleration ==> slowing down
What is positive and negative acceleration?
Positive acceleration occurs when an object's velocity is increasing over time, while negative acceleration (or deceleration) happens when an object's velocity is decreasing over time. Positive acceleration can be due to speeding up, turning, or changing direction, while negative acceleration is typically caused by slowing down or stopping.
How is a negative acceleration different from a positive acceleration?
A negative acceleration refers to a decrease in velocity, while a positive acceleration refers to an increase in velocity. Negative acceleration occurs when the speed of an object is decreasing, such as when it is slowing down. Positive acceleration occurs when the speed of an object is increasing, such as when it is speeding up.
Does acceleration have a negative or positive value if the velocity is increasing speed?
Acceleration has a positive value if the velocity is increasing speed. Positive acceleration means the object is speeding up.
Is retardation positive or negative acceleration?
Retardation is a form of acceleration that is negative, meaning that the object is slowing down. Positive acceleration refers to the object speeding up.
Does a softball have a positive or negative acceleration when it is thrown?
When a softball is thrown, it has a positive acceleration because its velocity is increasing with time as it moves through the air.
Can both the velocity and acceleration be negative?
Yes, both velocity and acceleration can be negative. Negative velocity indicates movement in the opposite direction of a chosen positive direction, while negative acceleration indicates a decrease in velocity in the chosen positive direction.
What happens when you put a negative acceleration and positive acceleration together?
When you combine a negative acceleration (deceleration) with a positive acceleration (acceleration), their effects add up algebraically. This means that the resulting acceleration will depend on the magnitudes of the two accelerations and their directions. If the positive acceleration is greater than the negative acceleration, the object will still be accelerating in the positive direction. If the negative acceleration is greater, the object will eventually decelerate and change 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.
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.
