What else can I help you with?
The speed of a car moving on a straight road is decreasing on applying the brakes its velocity and acceleration are in same direction?
If the speed of the car is decreasing while the car is still moving in a straight line, this means that the velocity and acceleration are in the same direction. This is because the car is decelerating, which results in a negative acceleration in the same direction as the velocity. This negative acceleration causes the speed of the car to decrease over time.
What will the direction of the resulting acceleration be If the net force on an object is in a negative direction?
It would be in the negative direction as well. Newton's Second law states that the acceleration of an object directly depends on the net force given to that object.
What happens to your speed if you have a negative acceleration do you speed up or slow down?
If you have a negative acceleration, you are slowing down. Acceleration is the rate of change of speed, so a negative acceleration means a decrease in speed.
Is it true when velocity decreases and acceleration arrows point in the same direction?
No, when velocity decreases and acceleration arrows point in the same direction, it means the object is speeding up in the negative direction.
What is a negative acceleration called?
You'll find a lot of people who call it "deceleration". But in real Physics, there's no such thing.There's only positive or negative acceleration, depending on whether the acceleration is inthe same or opposite direction compared to what you decided to call the positive direction.Negative acceleration is sometimes, but not always, associated with something that's slowing down.
Can velocity and acceleration be negative at the same time?
Yes
What is called negative accelarration?
Deceleration. Negative acceleration = Velocity is decreasing by time. Positive acceleration = Velocity is increasing by time. Zero acceleration = Velocity is the same by time.
The speed of a car moving on a straight road is decreasing on applying the brakes its velocity and acceleration are in same direction?
If the speed of the car is decreasing while the car is still moving in a straight line, this means that the velocity and acceleration are in the same direction. This is because the car is decelerating, which results in a negative acceleration in the same direction as the velocity. This negative acceleration causes the speed of the car to decrease over time.
Is the negative acceleration the same as deceleration?
Yes no doubt. It is a short term.
Can an abject have both positive and negative acceleration?
Yes, but not at the same time.
Can a car have negative velocity and negative acceleration?
It cannot have negative velocity, it can have negative acceleration.
Can there be a positive acceleration and a negative acceleration?
Yes, acceleration can be positive and negative because acceleration is a vector. It has both direction and magnitude. The direction is what makes it positive or negative. Negative acceleration is usually called deceleration.
What is negative and acceleration?
Positive acceleration = speeding up. Negative acceleration = slowing down.
Can a car have negative velocity and positive acceleration at the same time if traveling on a highway?
Yes.If the car is backing up, but slowing down, then its velocity is in the negative direction, and its acceleration is in the positive direction.
What will the direction of the resulting acceleration be If the net force on an object is in a negative direction?
It would be in the negative direction as well. Newton's Second law states that the acceleration of an object directly depends on the net force given to that object.
What is the decrease of speed called in physics?
Any change of velocity, including a decrease of speed, is described and measured as acceleration. Assuming the velocity and acceleration vectors point in the same direction, then in the case of decreasing speed, the magnitude of the acceleration is a negative value. Negative acceleration is often called deceleration, but that is just a special case of acceleration.
What happens to your speed if you have a negative acceleration do you speed up or slow down?
If you have a negative acceleration, you are slowing down. Acceleration is the rate of change of speed, so a negative acceleration means a decrease in speed.
