What is the difference bet increasing acceleration and increasing deceleration?
firstly, we should know what is meaning of accelerate i.e(to increase)that means acceleration is something which increases some physical quantity.In mechanics,acceleration means rate of change of velocity per unit time .a=v-u/twhere v=final velocity, u=initial velocity ,t=time& a=accelerationnow ,if the change in velocity is positive then i.e final velocity is greater than initial velocity.Suppose to be positive acceleration or simply acceleration.But when change in velocity is negative then acceleration is negative suppose to bedeceleration.Important thing is that acceleration is vector .so ,positive or negative accelerationindicates direction of acceleration.hence , force ,by Newton's second law.acceleration tends to increase the velocity of a moving body in the direction of motion while deceleration tends to decrease the velocity of the moving body applies in opposite direction of motion upto zero velocity after which it accelerate means increase velocity of the body but in opposite direction of initial direction of motion.

Does an object's speed increase even if acceleration decreases?
Acceleration is nothing but rate of increase in velocity. If acceleration at the time is positive velocity will increase independent of acceleration in past. Suppose you are moving at 5m/s at t=0. Acceleration is 5m/s2 initially. At t = 1 your velocity will be 10m/s. If acceleration became 3m/s2, then your velocity at t = 2 will be 13m/s. Thus your velocity still increased but comparatively lesser in amount. Now if acceleration became -8m/s2, velocity at t = 3 will be 5m/s, thus velocity decrease due to negative acceleration.

Is it possible for the instataneous velocity to have been negative at any time in the interval suppose the particle started at the origin x 0?
Yes. Since velocity is a vector it can have negative values when the object is moving in the direction opposite to the direction defined as the positive direction. For example, if an object is thrown vertically upwards and the upward direction is considered the positive direction, then when the object is falling downwards under gravity, its velocity is negative (in the upward direction). Coversely, if the downward direction is defined as the positive direction, then the object has a negative velocity during the first stage of the trajectory.
How do you solve for the rate of change in algebra?
The rate of change is often with respect to time t. suppose that d denotes the displacement of a particle, at time t, then you can find the speed with this formula:d=rt, then to solve for r we divide both sides by t and have d/t=rIn mathematics, it is useful to distinguish between velocity and speed. First, when considering motion of a particle in a straight line, specify a positive direction so that it is a directed line. Then the velocity of the particle is positive if it is moving in a positive direction and negative if it is moving in a negative direction. The speed of the particle is the absolute value of its velocity. In more advanced work, when the velocity is a vector v, the speed is the magnitude |v| of the velocity.
Does increasing the mass or velocity have the most affect on an object's kinetic energy?
Generally, the velocity as it is squared, but I suppose if you had some titanic mass moving at a very slow velocity then it could be the mass.

Suppose velocity is measured kmhr and time is measured in hourswhat is that unit of acceleration?
If velocity is km/hr and time is in hours then acceleration will be in km/hr2

How Can you tell from a velocity-time graph that the velocity is constant?
velocity is nothing but speed of a body in the given direction. suppose if body is moving with constant velocity then VT graph will be parallel to the X -axis, if not then the VT graph is not parallel to the X-axis it means then object is moving with different velocity or it has its dierection or both velocity and aswell as direction.
Suppose an ant walks counterclockwise on the unit circle from the point to the endpoint of the radius that forms an angle of 6.0 radians with the positive horizontal axis How far has the ant walked?
The question does not specify the starting point.
Does an object's speed increase even if acceleration decreases?
Acceleration is nothing but rate of increase in velocity. If acceleration at the time is positive velocity will increase independent of acceleration in past. Suppose you are moving at 5m/s at t=0. Acceleration is 5m/s2 initially. At t = 1 your velocity will be 10m/s. If acceleration became 3m/s2, then your velocity at t = 2 will be 13m/s. Thus your velocity still increased but comparatively lesser in amount. Now if acceleration became -8m/s2, velocity at t = 3 will be 5m/s, thus velocity decrease due to negative acceleration.
How was velocity of a wave derived?
The velocity=distance/time ,, Suppose that the distance covered is one complete vibration therefore the distance is called wavelength and the time is called periodic time then velocity=wavelength/periodic time also frequency= 1/periodic time therefore the velocity=wavelength*frequency
