Yes. For example, if you throw an object up into the air, this will happen when it reaches the highest point. At that moment, its velocity is zero; on the other hand, at any moment, the object is accelerating downward at 9.8 meters per square second.
Yes, for example, a car moving at constant speed.
Any falling object has acceleration and velocity vectors in the same direction.
The net force is in the same direction as the acceleration of an object.
If the acceleration is constant, yes. However, the acceleration of an object can vary. The rate of change of acceleration is called jerk.
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, for example, a car moving at constant speed.
As long as acceleration is zero, the object's velocity is constant.
Any falling object has acceleration and velocity vectors in the same direction.
It will increase the velocity of the the object in which the acceleration is applied.
The acceleration is the same direction of the velocity
No. Velocity is the change of location and accelarion is any change that occurs to the velocity of an object.
In that case, the object speeds up.
a = F/m, where a is acceleration, F is net force, and m is mass in kilograms.
When there is no resultant force there is no acceleration therefore the velocity will stay the same.
They all have to do with how fast an object is moving
The net force is in the same direction as the acceleration of an object.
If the acceleration is constant, yes. However, the acceleration of an object can vary. The rate of change of acceleration is called jerk.
