What happens to an objects speed if it travels with constant acceleration?
If an object travels with constant acceleration, its speed will change at a constant rate over time. The object's speed will increase if the acceleration is positive, decrease if it is negative, and remain constant if the acceleration is zero.
An object has initial velocity in the upward direction a final velocity in the downward direction and undergoes constant acceleration What can you say about its average acceleration?
The average acceleration of the object will be negative since it changes direction from upward to downward velocity. The acceleration will be constant because the object undergoes constant acceleration throughout the motion.
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.
Is it possible for an object with constant negative acceleration to change the direction in which it is moving?
Sure. 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.
Is the retardation means zero acceleration?
No, retardation refers to a negative acceleration, which means the object is slowing down. A zero acceleration means the object is moving at a constant velocity.
When the slope of v t graph is negative and constant what is the nature of acceleration?
acceleration is the slope of the v t graph... so the acceleration is constant and negative. In other words, the object is slowing down at a constant rate.
What type of acceleration does a trapezium on a velocity time graph represents?
A period of constant positive acceleration;a second period of zero acceleration; a third period of constant negative acceleration.
What happens to an objects speed if it travels with constant acceleration?
If an object travels with constant acceleration, its speed will change at a constant rate over time. The object's speed will increase if the acceleration is positive, decrease if it is negative, and remain constant if the acceleration is zero.

Changing velocty and constant acceleration?
Changing velocity and constant acceleration? Yes. Changing velocity indicates constant acceleration dv/dt = a constant(k) when v=kt. Then dv/dt= dkt/dt= k. the constant k can be positive , negative or zero.
What is positive negative and zero acceleration is?
positive acceleration is when things speed up; negative acceleration is when things slow down; and zero acceleration is when things do not speed up or slow down, this is called constant speed, or no change in 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.

Is the retardation means zero acceleration?
No, retardation refers to a negative acceleration, which means the object is slowing down. A zero acceleration means the object is moving at a constant velocity.
What is the effect on accelerationif we decreasing velocity?
If velocity is decreasing, acceleration is in the opposite direction of the initial velocity. If the velocity is decreasing at a constant rate, the acceleration is negative, causing deceleration. If the velocity is decreasing while changing direction, the acceleration may be a combination of negative and positive components.
How is acceleration represented on a graph?
Acceleration is represented on a graph by the slope of the velocity-time graph. A positive slope indicates acceleration in the positive direction, while a negative slope indicates acceleration in the negative direction. A horizontal line on the graph represents constant velocity, with zero acceleration.
How would a graph of negative and positive acceleration differ?
This depends on what the graph represents. If it is a graph of velocity on the vertical and time on the horizontal, then if acceleration is at a constant rate, the graph will be a straight line with positive slope (pointing 'up'). If acceleration stops, then the graph will be a horizontal line (zero acceleration or deceleration). If it is deceleration (negative acceleration), then the graph will have negative slope (pointing down).
