What is the direction of acceleration when moving in a circle?
The direction of the acceleration is towards the center. The magnitude of the acceleration is v2/r.
What number changes in the equation for a circle when you move the circle horizontally?
the number that is the x-coordinate
Does an object always move in the direction of the unbalanced force exerted on it by another object?
Not always, the unbalanced force only points in the direction of the acceleration so a body may be moving in the opposite direction. Example. A car moves with some speed to the right on a horizontal surface and lock the brakes, if the surface has friction, but the net force acting on it is equal to the frictional force pointing left and produces a Deceleration of carriage until stop, but while this happens continuously in motion to the right.
What direction is clockwise?
That means, the rotation is in the same direction as the hands of an analog clock or watch move. This is also known as rotating "to the right": if a circle rotates in a clockwise direction, then the upper part moves to the right.
What are the high speed high altitude air currents that circle earth in a westerly direction?
The answer is Jetstream.
A center directed what continuously changes the direction of an object to make it move in a circle?
gravity
What is the direction of acceleretion of a body in circular motion?
-- The acceleration is directed from the body to the center of the circle. -- The velocity is tangent to the circle at the place where the body is. That direction is also perpendicular to the acceleration at that moment.
If the moon in its orbit around earth behaves like a ball at the end of a string being swung above your head what forces are involved?
a centripetal force is a center-directed force that continuously changes the direction of an object to make it move in circle.
' uniform motion in a circle in which speed is constant but velocity is changing'?
This is because the term "velocity" includes a specification both of a speed, and a direction. The direction changes, therefore the velocity changes.
A passenger on a Ferris wheel moves in a vertical circle at constant speed. Are the forces on her balanced?
No. Since a force is a vector and the centripetal force caused by the rotation constantly changes direction, the net force is equally and continuously changing. Also... No, because there is an inward force.
If velocity dSdt and speed dSdt then what happened when a body move in a complete circle were dS0 then velocity?
Velocity is a vector, meaning it has a direction, like east, north, up. Speed isa magnitude without direction, 60 miles per hour is a speed; 60 miles per hour north is a velocity. When a care is going 60 mph in a circle the speed is constant but the velocity changes as the direction changes. The magnitude of the velocity is the same but the direction changes thus the velocity changes. Velocity changes if either the speed/magnitude or the direction change.
How circular velocity is constant in circular motion?
Velocity constantly changes as so does the direction around a circle...
What is the differnce between velocity and speed?
Velocity is a vector quantity. So direction is important But speed is a scalar. Body moving around a circle may go with uniform speed but not with uniform velocity as direction is changing continuously
Why is it an object can accelerate while travelling at constant speed but not at constant velocity?
Acceleration means the velocity changes. Velocity is made up of speed and a direction, so if only the direction changes, the velocity still changes, and therefore there is acceleration. The typical example is moving around in a circle.
Why the speed of an object is constant while the velocity is not?
This is not always the case. But if an object moves in a circle, at constant speed, its velocity will change. Velocity is a vector - consisting of the magnitude (the speed), and a direction. So by definition, if the direction changes, the velocity changes - you have a different vector.
How does an object's speed and motion change when it moves in a circle?
Velocity is a vector; having size (speed) and direction. The velocity of an object moving in a circle constantly changes, even if the speed is constant, because the object is continuously changing direction. Therefore it accelerates The force causing the acceleration is the centripetal force pulling it round into a circular path at right angles to the speed vector, like the moon going round the earth in a circular path being pulled towards the earth by the earth's gravity
Does speed change with velocity?
If the velocity changes, the speed may, or may not, change. The velocity can be thought of as having two components: a speed, and a direction. It is possible to change only the direction, for example, when an object moves in a circle at a constant speed. In this case, the velocity changes, but the speed does not.
