What else can I help you with?
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.
If the instantaneous velocity of an object is constant then so is acceleration.?
the velocity increases at a constant rate
What are three ways in which the velocity of an object may change when the forces on the object are unbalanced?
doing some homework? A net force vector/imbalance can either increase velocity (positive acceleration), decrease velocity (negative acceleration) or effect zero acceleration (perpendicular).
Which characteristics of motion could change without changing the velocity of an object?
Some characteristics of motion that could change without changing the velocity of an object include acceleration, direction, and position. For example, an object moving in a circle at a constant speed has a changing acceleration (centripetal acceleration), changing direction, but constant velocity. Similarly, an object can change its position while maintaining a constant velocity if it moves along a straight path.
What is the acceleration if the velocity is 0?
It's not possible to tell from only that much information. When you throw a rock up, its acceleration is the acceleration of gravity from the moment it leaves your hand until it hits the ground. But its velocity is upward some time, downward some time, and zero at the top.

Can a body have acceleration without velocity?
Yes, a body can have acceleration without velocity. This can occur if the body is changing its direction or speed while its velocity is zero at a particular moment. For example, a car at rest that suddenly accelerates forward experiences acceleration without velocity initially.

If a moving body has no acceleration does it mean that no force is acting on it?
It means there is no net force acting on it. A plane in the air has no acceleration, but it does have forces acting on it. Lift pushes it up Gravity pushes it down Air resistance opposes its movement Thrust provides movement When all these forces are equal the plane will move at a constant velocity. If one of these forces becomes greater the NET force on the plane will no longer be 0 and there will be an acceleration or deceleration. Hope that helps. Another example would be space as there are no opposing forces, if in space once a speed was that speed would be constant until you 1.) decelerated with a force in the opposite direction 2.) accelerated the speed past your current velocity in your current direction 3.) Get caught by some planets gravity and crash to you death (but then this question is the least of your problems)
What are some examples of acceleration questions that can be used to assess students' understanding of the concept of acceleration?
Some examples of acceleration questions that can be used to assess students' understanding of the concept include: What is the formula for calculating acceleration? How does acceleration differ from velocity? Can an object have acceleration if its speed is constant? Explain. Describe a scenario where an object experiences positive acceleration. How does mass affect an object's acceleration when the same force is applied?
What are the factors considered to cliam that an object is accelerating?
Some factors to consider to claim that an object is accelerating are changes in its velocity, direction, or both. Acceleration can be determined by calculating the rate of change of velocity over time or by observing a change in the object's position over time. A positive acceleration indicates that the object is speeding up, while a negative acceleration indicates that it is slowing down.
Is it possible for an object to have acceleration and no velocity?
It's possible for an object to have velocity equals to zero at some moment and to have some acceleration (when you throw a baseball upwards with the gravitation present, the ball reaches its maximum point and then starts to come back at its maximum height its velocity is zero while acceleration equals g).
