Yes. For example, if you throw a ball straight up in the air, it has a positive initial velocity, but the acceleration due to gravity is in the other direction. From your perspective, until the point when it starts coming back down it will be "decelerating" but really that's just acceleration in the opposite direction of the velocity.
Definitely.
-- When an object travels in a circle, like a satellite in a circular orbit, or
a roulette ball inside the wheel, the velocity points along the rim and the
acceleration points toward the center.
-- When a car is slowing down, the velocity points forward and the acceleration
points backward.
Yes, but only momentarily ... unless the object is in a circular orbit.
(Which would include a rock on a piece of string spinning around you.)
Yes. For example, an object that is slowing down has an acceleration opposite its velocity.
No. The direction of an object's acceleration is always
the same as the direction of the net force on it.
yes
yes, if the acceleration is in the opposite direction of the velocity.
Any falling object has acceleration and velocity vectors in the same direction.
acceleration is the increase of speed in a moving object. velocity is the speed and direction of a moving object.
The definition of acceleration is: Any change of velocity, that is, speed or direction of motion. If an object is undergoing constant acceleration, then the definition says that its velocity must be changing.
Yes. Acceleration is a change in velocity. As velocity is a vector (direction and speed) changing either the speed or direction will change the velocity and thus be an acceleration (or decelleration)
Yes, it is possible. For example, if you through an object up, its velocity would initially be in the "up" direction, but its acceleration would be in the "down" direction.
yes, if the acceleration is in the opposite direction of the velocity.
Any falling object has acceleration and velocity vectors in the same direction.
acceleration is the increase of speed in a moving object. velocity is the speed and direction of a moving object.
The definition of acceleration is: Any change of velocity, that is, speed or direction of motion. If an object is undergoing constant acceleration, then the definition says that its velocity must be changing.
Yes, it can happen. when the velocity is momentarily zero while an object is changing from moving in the positive direction motion to the negative direction; the object obviously will stop at one point, but will still have a constant acceleration.
FALSE. Acceleration is the change of speed and/or direction of an object.
The change in velocity is just the change in velocity. The RATE of change of velocity - how quickly velocity changes - is usually called "acceleration".
Yes. Acceleration is a change in velocity. As velocity is a vector (direction and speed) changing either the speed or direction will change the velocity and thus be an acceleration (or decelleration)
Anytime an object is slowing down, its acceleration is in the opposite direction to its velocity.
Yes, acceleration is the how the velocity changes. This also includes when an object turns
Acceleration is the change in velocity of an object over time. Take note that velocity is a vector quantity which means that it has magnitude and direction...Thus...An object undergoes acceleration when:1. there is a change in the magnitude of the velocity (speed) of an object.2. there is a change in direction of an object.3. it changes both in direction and magnitude.
