Difference between negative and positive acceration?
Positive acceleration ==> speeding up Negative acceleration ==> slowing down
What is the acceleration if someone walks at 5 kilometers an hour for 2 hours?
If the person has not been speeding up or slowing down, his acceleration is 0 km/s/s.
What is the acceleration of a car that moves at a steady velocity of 100 kmh for 100 seconds Explain your answer and state why this question is an exercise in careful reading as well as in physics?
Acceleration = 0 because the car is moving at a STEADY velocity. It is neither speeding up, nor slowing down.
If speed is zero then is acceleration zero?
There are only 3 ways to accelerate: speeding up, slowing down, and changing direction. since 0mph allows you to do none of those three things, it can't be accelerating.
What must cause acceleration when a car is moving a constant speed and why?
Acceleration is scientifically defined as a change in velocity, not an increase in speed. Thus slowing down, speeding up, or changing direction are all forms of accelerating. If one is moving at a constant speed, then the only way to accelerate would be to change direction.
Is a car that is speeding up acceleration?
no
What is negative and acceleration?
Positive acceleration = speeding up. Negative acceleration = slowing down.
What is meaning of acceleration?
The process of speeding up
What is an example of acceleration in a car?
Speeding up.
When does an object have no acceleration?
When it is stationary, or when the velocity is constant. If it is speeding up or slowing down, it has acceleration.
What is positive acceleration negative acceleration?
Positive is speeding up and negative is slowing down
What is meant by de-acceleration?
de acceleration just means slowing down. Acceleration means speeding up. Actually any change in speed is considered to be acceleration. Slowing down is called negative acceleration or (de-acceration) and speeding up is called positive excelleration.
What can positive acceleration called?
Positive acceleration could be called "speeding up" if you felt like it.
How does the direction of the acceleration along determine if the object is speeding up or slowing down?
Take the component of the acceleration along the direction the object is moving. If this component is positive (the acceleration vector, or the relevant component, points in the same direction as the movement), then the object is speeding up.
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.
What is the Synonym for Acceleration?
hastening, hurrying, stepping up, speeding up, quickening
When an object is speeding up to the right what direction is the acceleration?
The acceleration would be in the direction of the object's motion, which is to the right.
