It depends on which direction you are resolving the acceleration from. If you use the original direction of the car as it turns it is decelerating as the speed it is moving in that direction is decreasing. If you resolve from the direction which the car will be going towards then it is accelerating as its speed in that direction is increasing.
Acceleration is any change in velocity. It could be a change in speed or direction. Technically, even slowing down is acceleration.
Yes. Even though its speed doesn't change, its velocity does change, therefore it is accelerating.
Yes.
You are driving your car with cruise control but you steer around a bend in the highway. The cruise control keeps your speed constant, but by steering you change your direction and thus your velocity is not constant.
constant speed=0 acceleration Acceleration is the change in speed. If the speed doesn't change(ie constant) the acceleration is zero.
An object with a constant (vector)velocity is not accelerating. An object with a constand (scalar)speed can actually be accelerating, a car with a constant speed that passes around a corner is changing direction and is subjected to a lateral acceleration.
Yes. The simplest example is an object moving at a constant speed in a circle.
That is possible, for example, if an object moves around in a circle. In this case, the velocity changes all the time; the speed does not.
Acceleration is change in velocity. These are vectors that have magnitude and direction. Changing either magnitude (speed) or direction will have the skater be accelerating. SO, if the skater is going at a constant speed of 2m/s in a straight line, he is not accelerating. If he is at a constant speed of 2m/s traveling in a circle (you gave the word "around"), he is accelerating. Going around in circles means there is a force constantly changing your direction. Obviously that force is coming from the skaters legs.
If it's going at a constant speed then it is not accelerating. To accelerate would mean to have a rate of change for speed in some direction. If the ball is going outward while traveling at a constant speed due to centrifugal force then it is accelerating. If it's going inwards due to some ground angle then it is also accelerating. From Newton's laws we know that to have a circular motion, an object must be subject to a force directed to the centre of the structure and is accelerating in that direction. This centrifugal force, exerted by the structure to the ball, is opposite in direction and magnitude to the 'fictitious' centrifugal force.
Acceleration is any change in velocity. It could be a change in speed or direction. Technically, even slowing down is acceleration.
A body is being accelerated if its speed OR direction are changing.A satellite in a perfectly circular orbit around the earth ... like a TV satellite ... is moving at constant speed. But, technically, since its direction is always changing, to keep it on a circle, it's experiencing constant acceleration.
Yes, the satellite is accelerating because it is revolving around our earth and in a circular motion so its velocity changes every second so it is accelerating.A2. No, the satellite is not accelerating. Acceleration is defined as the rate of change of velocity. But, its velocity is constant. The centrifugal effect is exactly balanced by the pull of gravity (assuming a circular orbit).But a nice question. The net acceleration between these forces is zero.
This buzzing noise is likely a faulty wheel bearing. The bearings are moving around randomly and need to be replaced.
Your body cannot sense constant velocity. For example, you cannot sense that the earth is turning nor can you sense that the earth is orbiting around the sun. And, if you are in a vehicle that is traveling with a constant velocity, you cannot sense that you are moving unless your eyes sense a change in position.
Its because all of these movements are constant, they are not accelerating or slowing down. We only feel a force when there is acceleration or decelleration. If you accelerate in a car, you are pushed back into your seat as the force effects you and everything in the vehicle. But at constant speed in a straight line, you can move about normally, as if you were at a standstill.
Yes. Even though its speed doesn't change, its velocity does change, therefore it is accelerating.
