An object is accelerating if any of these things are happening . . .
-- its speed is increasing
-- its speed is decreasing
-- its direction is changing.
The object may be accelerating even if its speed isn't changing.
Acceleration does not mean "speeding up".
The speed of the object will increase.
The speed of the object will increase.
It slows down.
The speed increases. The object accellerates positively in the direction of motion.
No. An object in free-fall accelerates at a constant rate of acceleration.Its speed grows at a constant rate.
The speed of the object will increase.
The speed of the object will increase.
The speed of the object will increase.
It accelerates as long as the force is applied, and after that it continues at a uniform speed and direction.
It slows down.
The speed increases. The object accellerates positively in the direction of motion.
Decelerate means to slow down.
It accelerates as long as the force is applied, and after that it continues at a uniform speed and direction.
No. An object in free-fall accelerates at a constant rate of acceleration.Its speed grows at a constant rate.
When an object accelerates it can change its speed or direction of motion. When it accelerates without changing its direction of motion, it can cover any distance in less time.
The object that is moving at a constant speed will slow down. Its new velocity will be determined by the original constant speed along with the new combined mass of the moving object and the additional "large mass."
Then the result will be the same as if NO forces act on the object (since the sum of the forces is zero). The object will continue moving in a straight line, at constant speed.
