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.
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 information would you need to know in order to calculate an object's acceleration?
According to Newton's law. Force = mass x acceleration. If you know the force acting upon an object and the mass of the object you can easily calculate the acceleration it will experience.
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)
Does it mean a skydiver is slowing down if the acceleration of the skydiver decreases as falling progresses?
No.Acceleration is a measure of the rate of change of velocity (speed & direction). If acceleration is decreasing (but still above zero) then this means that the rate at which the speed is increasing in this direction is decreasing.As long as the downward acceleration is greater than zero then the skydiver's speed is still increasing.Once terminal velocity is reached then downward acceleration will equal zero (speed is constant).If the downward acceleration falls below zero (as will happen once his parachute is deployed for instance) then this means he is slowing down.
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.
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.
What happens to an object's motion when 2 equal forces act on an object in opposite directions?
Nothing! If the two forces are equal and opposite then they will cancel each other out. What will happen next is described in Newton's First law when it says "An object in motion will stay in motion unless acted upon by an outside force". Two equal and opposite forces have the same effect as no force, therefore the object's motion will remain the same as if it had never been acted upon by the two opposite forces.
What happen when opposite forces acting on an object are balanced?
Assuming this is a physics question, when all the forces acting on an object are balanced, the object is in equilibrium. For example, when a car is at a constant velocity, with no acceleration, all the forces are equal.
What will happen if the earth starts to rotate and revolve in the opposite directions?
The season progression would reverse.
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 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
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.

How could an object accelerate while still traveling at a constant speed?
Acceleration means the velocity changes. Velocity is made up of speed and a direction, so if only the direction changes, the velocity still changes, and therefore there is acceleration. The typical example is moving around in a circle.
