What has to happen to a car's acceleration and velocity for a car's speed to increase and have a positive acceleration?
For a car's speed to increase and have a positive acceleration, the car's velocity needs to be increasing in the same direction as its acceleration. This means that the car is speeding up. When the velocity and acceleration have the same sign (both positive or both negative), the car's speed will increase.

When is the acceleration of a body is positive?
A body's acceleration is positive when its velocity is increasing over time. This can happen when the body is speeding up in the same direction as its velocity, or when it is slowing down in the opposite direction of its velocity. Both scenarios result in a positive acceleration value.
What does a positive acceleration mean?
Positive acceleration means that an object's velocity is increasing over time. This can happen when an object is speeding up in the direction of its motion.
What would happen to an object's velocity if positive work was done on an object?
If positive work is done on an object, its velocity will increase. This is because work done on an object transfers energy to the object, which can result in an increase in its kinetic energy and thus its velocity.
When a car's velocity is negative and its acceleration is positive what is happening to the car's motion?
The car is slowing down
What will happen to the balls velocity as it falls farther below the point of relase?
As the ball falls farther below the point of release, its velocity will increase. This is due to the acceleration caused by gravity pulling the ball downward. The acceleration will cause the ball to speed up as it falls.

What does a positive acceleration mean?
Positive acceleration means that an object's velocity is increasing over time. This can happen when an object is speeding up in the direction of its motion.
What happen to an object when it has positive acceleration?
Either of these is referred to as positive acceleration: A) the object's velocity is increasing in the frame of reference B) the object is being moved in a positive direction in a coordinate plane
What would happen to an object's velocity if positive work was done on an object?
If positive work is done on an object, its velocity will increase. This is because work done on an object transfers energy to the object, which can result in an increase in its kinetic energy and thus its velocity.
When velocity is negative and acceleration is zero what happen the object in the motion?
It accelerates in the opposite direction. Its velocity increases in the opposite direction to the direction that has been assigned positive.
When a car's velocity is negative and its acceleration is positive what is happening to the car's motion?
The car is slowing down
What will happen to the balls velocity as it falls farther below the point of relase?
As the ball falls farther below the point of release, its velocity will increase. This is due to the acceleration caused by gravity pulling the ball downward. The acceleration will cause the ball to speed up as it falls.
An object with a constant acceleration but with zero velocity what is mean is n't possible.?
Yes, it can happen. when the velocity is momentarily zero while an object is changing from moving in the positive direction motion to the negative direction; the object obviously will stop at one point, but will still have a constant acceleration.
Can the velocity of object reverse direction when its acceleration is constant?
Yes, the velocity of an object can reverse direction even when its acceleration is constant. This can happen when the object is subjected to an acceleration in the opposite direction to its initial velocity, causing it to slow down and eventually reverse direction.
Can direction of velocity of a body change when its acceleration is constant?
Yes, the direction of velocity of a body can change even when its acceleration is constant. This can happen if the acceleration and initial velocity of the body are not aligned in the same direction. The body will still experience a change in velocity due to the constant acceleration, which can lead to a change in direction.
How many types of velocity?
Velocity can either increase or decrease. It can do so at either an increasing or decreasing rate (positive or negative acceleration)
Why is the velocity of accelerated body may be zero?
The velocity of an accelerated body may be zero when it temporarily stops moving at a specific point during its acceleration process. This can happen if the body changes direction or experiences a deceleration that causes its velocity to drop to zero before changing again to increase its velocity in the opposite direction.
