Can an object be at rest and accelerate at the same time?

Answer: Yes, acceleration is a change in velocity, so an object might be momentarily at rest but a split-second later have some speed, i.e. it can be changing its velocity even if it is momentarily at rest. An example is a vertically thrown ball at the top of its trajectory, or a yo-yo just as it turns around.

What are the three things that could be happening that tells you an object is accelerating?

There are three ways an object can accelerate: a change in velocity, a change in direction, or a change in both velocity and direction.

How can the velocity of an object change when its acceleration is constant?

Sometimes an accelerating object will change its velocity by the same amount each second. This is referred to as a constant acceleration since the velocity is changing by a constant amount each second. An object with a constant acceleration should not be confused with an object with a constant velocity.

Can an objects velocity change direction when its acceleration is constant example?

A object undergoing a constant acceleration has a constantly changing velocity. If the acceleration always points in the same direction as the velocity, the trajectory will be no different than if there were no acceleration, but in general acceleration will change the trajectory. Yes it can.

When an object is at rest in the beginning of its motion what is its initial velocity?

1.At rest means zero velocity. In the beginning means initial. So the answer is zero.

When an object is at rest What is its acceleration?

If we think about the problem quickly, it might seem the acceleration must be zero. At one moment, we’re not moving, and a small time later we’re still not moving, so there has not been a change in speed. Therefore, the acceleration has to be zero.

What is an object doing if its initial velocity and acceleration are in opposite directions?

If the velocity and acceleration are in the same direction (both have the same sign – both positive or both negative) the object is speeding up. If the velocity and acceleration are in opposite directions (they have opposite signs), the object is slowing down.

When an object is released from rest and falls in the absence of friction what happens to its motion?

When an object is released from rest and falls in the absence of friction, which of the following is true concerning its motion? Its velocity is zero and its acceleration is not zero.

When an object is released from rest and falls in the absence?

When an object changes velocity and direction you are experiencing?

An object which experiences either a change in the magnitude or the direction of the velocity vector can be said to be accelerating. This explains why an object moving in a circle at constant speed can be said to accelerate – the direction of the velocity changes.
