Zero acceleration means that the velocity doesn't change. It doesn't mean that there is no velocity.
Yes. An object slowing down but still moving in a positive direction has a positive velocity but a negative acceleration.
No, acceleration is a CHANGE in speed, something with 0 acceleration while not changing speed can still be moving.
it can be moving at constant velocity or staying still
i am ten so this will be a wimpy answer. it is an object that has nothing to propel it and therefor it has no acceleration. see wimpy Actually the above is wrong because an object can still be moving but it is accelerating only when there is a change in speed or direction. A car moving at a constant speed of 50 m/h is not accelerating however we can agree that it is still moving.
then that object experiences no acceleration, meaning it will maintain its speed. if still it will remain still, if moving, it will continue moving. newtons first law
When the forces on an object add up to zero, the object's acceleration is zero. Thatmeans the speed or direction of its motion doesn't change. It does not mean thatthe object isn't moving. A moving object would just keep moving at a constantspeed in a straight line.
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.
If, for example, there's a cup on a table, it's not moving, but since the Earth rotates, it still has movement.
When an object slows down it is still accelerating.
it is actually a non example of acceleration is when it is not moving /not accelerating and it is like when a car with its own cruise control set
Yes. A car that brakes is slowing down and therefore has negative acceleration, but is still moving forward a therefore has positive velocity because it cant all of a sudden stop.
Yes an object can be accelerate if its moving along a curve path because when the object moves along a curve path it has constant speed and there is still change in velocity and change in velocity has acceleration
No, an object with zero velocity does not necessarily have zero acceleration. The best example of this is an object that is thrown into the air. Let's look at that.The object that is lofted up is constantly accelerated by gravity. The object will have some initial velocity, and its velocity will decrease under the influence (the constant acceleration) of gravity. At some point it will "stop" in air for an instant, and the velocity of the object will be zero. But gravity has always been accelerating the object, and it will continue to do so, pulling it back down to earth. The object was accelerating at g, which is the earth's gravitational constant, even during the instant that it was not moving.Sooooo....in the above explanation, Quirkyquantummechanic appears to have successfully argued that "zero acceleration" is, in fact, a degree of acceleration, and is not the same as "no acceleration". Also, QQM indirectly pointed out that an object approaching zero velocity also approaches zero acceleration, and at the precise moment of zero velocity, the object is at zero acceleration albeit still under the influence of acceleration.Therefore, the answer to the original question is still "Yes" - an object at zero velocity does have zero acceleration.
to an object that stays still
Since force is a function of acceleration and an object at rest has zero acceleration, then then net force is zero as well.
The answer is yes and no.Acceleration is the rate of change of velocity. Velocity is speed plus direction.If an object is travelling eastward and slowing down in a straight line then its velocity is decreasing, it is still travelling eastward. However the force slowing the object is a westward force.A reducing acceleration (slowing down) is most often called a deceleration or negative acceleration. So you have a negative eastward acceleration.
Force is defined as mass times acceleration. In relativistic physics, we see that mass can change, for example, as an object approaches the speed of light it becomes more massive. When you apply force to such an object, you will still get some amount of acceleration, but possibly a very small amount, and you may also get an increase in mass. If the object had been moving at a slower speed you might have observed a greater acceleration and no increase (or no detectable increase) in mass. But in either case, the product of mass times acceleration remains the same.
Yes. It won't have zero velocity for long, but it's possible for the instantaneous velocity to be zero when the acceleration is non-zero. For example, if you throw a ball straight up, at the very top of its path it's not moving upward or downward, but it still has an acceleration, and will fall from that point starting immediately.
Inertia is the tendency of an object to remain still, or remain moving at a constant speed in a straight line, unless acted upon by an outside force. Thus the measure of this quality is the mass of an object since acceleration is equal to the force applied to an object multiplied by its mass. The greater the mass, the less acceleration a given force will impart to it. In order to impart greater acceleration to a given mass, greater force is needed.
Friction is independent of speed because an object could not be moving and still have so friction.
"What is the force exerted by a still liquid on an immersed non-moving object called? -- PressureOtherwise, if the object is moving, one could also have "shear forces".
Force causes acceleration, not motion. A moving object undergoing zero net force will continue to move in the same direction at the same speed.
2 Forces are unbalanced when an object that is not moving starts moving or changes speed or direction. Balanced forces are the opposite they are where an object that is not moving stays still or an object that is moving stays at a constant pace.
If you add up all the forces acting on an object, they are balanced if they equal zero. (They cancel each other out). If the forces acting on a object are balanced, then the acceleration of that object is zero. It may still be moving, but it is not accelerating. An object that is not accelerating, (the sum of the forces acting on it is zero), is in equilibrium.
If there is no net force acting on an object then the movement of the object doesn't change. If it is sitting still, then it remains sitting still. If it is moving, then it continues moving at the same speed in the same direction.
