What has to happen to a car's acceleration and velocity for a car's speed to increase and have a positive acceleration?

The velocity has to increase in a positive direction. The increase in velocity in a positive direction is a positive acceleration.

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)
What would happen if terminal velocity did not occur?
When the speed (of falling) is increased, the force of gravitation will be the same, but the air resistance will increase. At some speed, the two will be in balance - there will be no more acceleration, and the object is said to have achieved terminal velocity.
What happen to object with velocity and acceleration in opposite directions?
It slow down, and eventually reverse direction.
What will happen to the velocity of the car as sand is loaded onto it?
the velocity of a car is be reduced when sand is loaded onto it owning to the fact that there is increase in mass of the car
Do you agree with the statement an object with a zero velocity can have an acceleration greater than yero?
Of course. Toss a stone straight up. -- From the moment it leaves your hand until the moment it hits the ground, it has constant acceleration ... the acceleration of gravity, around 10 meters per second2. The number isn't important, only the fact that the acceleration of the stone is not zero until it hits the ground. -- Velocity-wise: The stone starts out with some upward velocity, which steadily decreases until it's at the top of its arc, then the velocity becomes downward and increases until the stone hits the ground. -- At the very top of the arc, there is a point where the velocity changes from upward to downward. In order for that to happen, there must be an instant when the velocity is zero. -- But the acceleration is constant and not zero, even at that instant when the velocity is zero.
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
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.
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)
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.
What would happen to an object in free fall?
The velocity in the x direction would be constant because gravity only affects the vertical components of objects. The velocity in the y direction would increase due to the constant acceleration due to gravity. The acceleration due to gravity on Earth is always -9.81 m/s^2.
If the mass of abject increases what will happen to its acceleration if the same amount of?
it will increase.
What would happen if terminal velocity did not occur?
When the speed (of falling) is increased, the force of gravitation will be the same, but the air resistance will increase. At some speed, the two will be in balance - there will be no more acceleration, and the object is said to have achieved terminal velocity.
What happen to the acceleration of the cart as you decrease the the washers in the pan?
Decreasing washers in the pan decreases mass, so acceleration should increase.
What happen to object with velocity and acceleration in opposite directions?
It slow down, and eventually reverse direction.
What is a change in velocity or direction?
Any change in speed or direction is a change in velocity. That's an acceleration,and it directly implies the presence of force, since it can't happen without force.
What will happen to the velocity of the car as sand is loaded onto it?
the velocity of a car is be reduced when sand is loaded onto it owning to the fact that there is increase in mass of the car
