What else can I help you with?
How can you have negative acceleration but not negative speed?
The negative part in negative acceleration is indicating direction, as acceleration is a vector quantity. Speed however, is a scalar and has magnitude only and therefore cannot be negative. An example could be -2.6ms-2 meaning that there is an acceleration of 2.6ms-2 but in the opposite direction to other vectors.
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.
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.
Difference between negative and positive acceration?
Positive acceleration ==> speeding up Negative acceleration ==> slowing down
What is a real life example of negative acceleration?
A real-life example of negative acceleration is when a car slows down to a stop at a red light. As the driver applies the brakes, the car's velocity decreases, resulting in negative acceleration.
What is another name for acceleration?
In general, slowing down is negative acceleration. Some might call it deceleration. Braking a car or bike is a simple example of negative acceleration.

A car approaching a red light is an example of?
Negative acceleration
Can acceleration be a negative number?
Yes, acceleration can be a negative number. Negative acceleration means that the object is slowing down, or changing its velocity in the negative direction. It indicates a decrease in speed or a change in direction opposite to the initial motion.
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.
Can an object have a negative acceleration and be speeding up?
Yes, an object can have a negative acceleration and still be speeding up. This occurs when the direction of the acceleration is opposite to the direction of the object's velocity. For example, if a car is moving forward with a velocity of 20 m/s and experiences a negative acceleration of -2 m/s^2 (deceleration), it will be speeding up while slowing down.
When final velocity is less than initial velocity is an example of?
Deceleration (or negative acceleration).
What is negative and acceleration?
Positive acceleration = speeding up. Negative acceleration = slowing down.
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.
A sentence for negative acceleration?
Yes, negative acceleration is slowing down. Take the example of a car going from 0 to 60 mph this would be positive acceleration. If once it reaches 60 mph the foot is removed from the petal the car will continue to move but due to friction and wind resistance it will begin to slow down, while slowing down it is in negative acceleration.
