False. At least the way "acceleration" is described in physics, acceleration involves any change in velocity - so the "accelerating" object can speed up, slow down, or simply change direction.
For an object's speed to change (increase or decrease), the object must be accelerating. If there is an acceleration, there is a non-zero net force acting on the object.note: Velocity and speed are different. An object's velocity can change without the speed changing. Example of this is centripetal acceleration. The object's velocity changes directions, thus the velocity changes. The magnitude (or speed), however, stays the same (if only a radial acceleration is present).
Yes, but only at one instant. For instance, if you throw an object straight up, when it reaches the highest point its instantaneous speed is zero, but of course its speed is changing - thus, acceleration is non-zero.
Acceleration is the change in velocity and/or What_three_ways_can_acceleration_change_an_objects_motionof an object. Acceleration can either speed an object up, slow it down (deceleration), or change the direction in which the object is moving.
If you are moving at a speed of ceratin speed and there is no force trying to slow you down, and there is no force trying to speed you up. Then there is zero acceleration. An example would be : an object in out in space, if you throw a object away from you the object will float away, since there is no force working on the object after you throw it the object is moving away in a locked speed from you, but have zero acceleration because there is no force affecting the object

The acceleration is the same direction of the velocity
There is a huge difference between constant speed and constant acceleration. Constant speed is when the object is travelling constant, no change in its velocity and acceleration or in other words no extra force to speed up. Constant acceleration when the object is acceleration constant, it means that the speed of the object is change at the same rate each second. The acceleration rate at which the object is travelling is constant. for example, when a car is stationary at a traffic light and it starts acceleration, picking up speed but the rate of acceleration will not constant because the amount of force applied differs each second due to the acceleration rate.

Acceleration
If you are moving at a speed of ceratin speed and there is no force trying to slow you down, and there is no force trying to speed you up. Then there is zero acceleration. An example would be : an object in out in space, if you throw a object away from you the object will float away, since there is no force working on the object after you throw it the object is moving away in a locked speed from you, but have zero acceleration because there is no force affecting the object
The acceleration will either speed up or slow down an object's motion in the direction it is applied. Any change in speed or direction is considered acceleration.
force can speed up, slow down, and/or change direction of an object commonly refered to as acceleration
If an object's speed is changing ... either growing or shrinking ... or the direction of its motion is changing, or any combination of these changes, then the object is said to be accelerated.
Its acceleration due to gravity is constant. The acceleration is equal to the object's change in speed every second. I've tried to illustrate the constantly-increasing falling speed in my diagram below.
