What else can I help you with?
Can a direction of velocity of an object reverse at constant acceleration?
Yes, the direction of an object's velocity can reverse even when it is experiencing constant acceleration. This can happen if the acceleration is in the opposite direction to the object's initial velocity.
Can a velocity be reversed if acceleration is constant?
Sure. A pendulum, a child's playground swing, and a bullet shot straight up all have constant acceleration, and all reverse direction.
Can the velocity reverse the direction when acceleration is constant?
Yes, it can, if the initial velocity vector of an object was in opposite direction to its constant acceleration. Example: Anything you toss with your hand has constant acceleration after you toss it ... the acceleration of gravity, directed downward. If you toss it upward, it starts out with upward velocity, which reverses and eventually becomes downward velocity.
Acceleration is negative if?
Acceleration is negative if the object is slowing down or moving in the opposite direction of the velocity vector.
An object that reverses direction while its acceleration remains constant?
An object can reverse direction anytime its velocity is in the opposite direction of its acceleration.A good example is throwing a ball straight up into the air. As soon as the ball leaves your hand, the acceleration due to gravity begins to slow it down. Even though the initial velocity is going straight up, once the ball leaves your hand the acceleration is constantly pulling the ball back towards earth. The ball eventually reaches its peak height, and reverses direction, falling back to earth. This all happens while the acceleration remains constant.

Can an object with a constant acceleration reverse its direction of travel?
Of course. Anything you toss with your hand has constant acceleration after you toss it ... the acceleration of gravity, directed downward. If you toss it upward, it starts out with upward velocity, which reverses and eventually becomes downward velocity.

What characterizes constant velocity motion on a position time graph?
A straight line with a constant slope. But the reverse is not true. A straight line with a constant slope only means constant speed in the radial direction. The velocity may have components at right angles to the radial direction that are changing.
Can you site an example in which the acceleration of a body is opposite in direction to its velocity?
When an object is thrown upwards, the acceleration due to gravity pulls it downwards, opposite in direction to its initial velocity. This causes the object to eventually come to a stop and reverse its direction as it falls back down.
What happen to object with velocity and acceleration in opposite directions?
When an object has velocity and acceleration in opposite directions, it means the object is slowing down. The acceleration is acting against the velocity, causing the object to decelerate. This situation can occur when an external force is applied in the opposite direction of the object's motion.
Can an object reverse its direction while maintaining a constant acceleration?
One answer to this is that all object are in motion all of the time relative to all other objects. With that said, in the context of permanent halt" the only way that an object can be perceived as "halted" is by another object with the same velocity.
When an object's initial velocity is less than its final velocity what does that indicate?
AccelerationWhen the velocity of an object increases or decreases, that means it has accelerated. Acceleration is defined as the rate of change of velocity.If an object's final velocity is greater than its initial velocity, that indicates positive acceleration. If an object's final velocity is less than its initial velocity -- if, say, it slows down and comes to a stop -- then that indicates negative acceleration. Deceleration is another way of saying negative acceleration. But . . .It is good idea to avoid using the term deceleration, because an object that is experiencing negative acceleration may slow down, come to a stop momentarily, and then reverse direction and speed up -- IN THE OPPOSITE DIRECTION!You can think of it this way: When an object is slowing down, its acceleration is in the direction opposite to its motion. We think of that as negative acceleration.
Will the acceleration be zero if velocity is constant in velocity time graph?
Yes, by definition, Acceleration is the derivative of velocity. From Calculus, we know, the derivative of any constant function is simply 0. Therefore, any velocity time graph containing a constant velocity function will have an acceleration function = 0. c'=0 or c d/dx=0 also, there is a very simple, and nice progression to things in the field of Kinematics. where given a function, whether it be position, velocity, or acceleration, you can find the other through calculus. the progression for integration goes as follows, jolt (the feeling you get when acceleration changes), acceleration, velocity, position. And the reverse for derivatives. Having a velocity function of something like 55mph, think of it as driving on the freeway, absent of outside forces of friction, air resistance and hills, you never have to accelerate (positively, or negatively) to maintain speed, and the math backs that up. 55 is constant, and the derivative is 0. now if you had a velocity function such as 2x^2 + 5, also known as a parabolic function, you would take the derivative and get an acceleration of 4x, and a jolt of 4, and if you integrate to get position, you would have 2/3x^3+5x. Its all about the math.
