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.
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.
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.
Yes, a merry-go-round is accelerating even if it has a constant speed because acceleration includes changes in direction as well as changes in speed. In this case, the merry-go-round is constantly changing direction as it spins around the central axis, so it is undergoing acceleration.
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.
Even though the person is moving at a constant speed, they are changing direction constantly as they go around the track. Since acceleration is defined as any change in velocity, and velocity includes both speed and direction, the person running on a circular track is experiencing acceleration.
An object in orbit is constantly accelerating towards the center of the body it is orbiting due to gravity. The speed of the object remains relatively constant, but its direction of motion is continually changing as it orbits around the central body. The shape and size of the orbit also remain constant if there are no external forces acting on the object.
This buzzing noise is likely a faulty wheel bearing. The bearings are moving around randomly and need to be replaced.
