WHAT DOES IT MEAN IF THE DIRECTION OF THE ACCELERATION OF AN OBJECT IS THE SAME AS THE DIRECTION OF MOTION OF THE OBJECT?

IF THE DIRECTION OF ACCELERATION FOR AN OBJECT IS OPPOSITE TO THE DIRECTION OF MOTION OF THE OBJECT,WHAT DOES THAT MEAN?

AND WHAT IF THE INITIAL VELOCITY OF AN OBJECT IS ZERO BUT THE ACCELERATION IS NOT ZERO??????? :confused: :confused: WHAT DOES THAT MEAN?

This place is DEAD tonight.

I'm home sick as can be and there is nobody around.

Faiza,

Get a grip! You're all over the place having an anxiety attack. Take a deep breath and count to 10!

Feel better?

Acceleration means the rate of change of velocity. It can be positive or negative, i.e., it can tend to increase the velocity or make it decrease.

Both acceleration and velocity are vectors. That means they have magnitude and direction. If you are driving along in your car and you press the gas pedal then both your velocity and acceleration are in the same direction and your velocity (speed) will increase. If you apply your brakes then your acceleration is negative meaning your velocity and acceleration are in opposite directions.

Likewise, if you are backing your car and apply the accelerator both your velocity and acceleration are negative (in the same direction) and your speed increases. Applying your brakes while backing up makes your acceleration positive while your velocity is still negative but, fortunately, your speed decreases.

Okay, so if the direction of the acceleration is the same as the direction of motion
of an object, that means the object will increase speed????????? And if the direction of the acceleration is opposite to the direction of motion of a object, the object will decrease in speed??
