Give reason why uniform circular motion is considered as accelerated motion?
Because within circular motion, acceleration is constant
What is the difference between uniform linear motion an uniform circular motion?
linear is which is on a straight path and circular motion is which has a curved path. *In a uniform linear motion,the velocity is constant and the acceleration is zero.So,uniform linear motion is an unaccelerated motion. *In uniform circular motion the velocity can be variable although the speed is uniform.So,it is an accelerated motion.
Is planetary motion a uniform motion?
Planetary motion almost fits into the category of Uniform Circular Motion. Uniform Circular Motion is an object moving around a circle of constant radius at a constant speed. The planets fill all of these requirements except for the fact that their orbits are slightly elliptical. Their orbital paths are almost perfect circles, but they are so close that for Uniform Circular Motion problems, it is not likely that considering the orbits to be circular will…
Uniform and non-uniform motion?
if a body performs motion with constant speed along a circular path,its motion is called uniform circular motion. here,note that speed remains constant , not velocity. direction of velocity of a body in uniform circular motion, is different at each point on the circular path. consider a body performing uniform circular motion along the circle of radius'r' in anticlock wise direction. when this object is on points a,b,c,d and e, directions of its velocity are…
What is uniform and non uniform motion?
Think of uniform as everything moving together. For example, in uniform circular motion describes the motion of a body traversing a circular path at constant speed. The distance of the body from the axis of rotation remains constant at all times. If the motion was non-uniform the distance of the body from the axis of rotation would vary.
What is the correct name for circular motion?
If the motion is truly in the form of a circle, the phrase uniform circular motion describes it appropriately. This means that the object is in a constant state of motion about a fixed point at a constant distance from that point. Circular motion can be considered an acceleration, because an acceleration describes any change in velocity or direction. Since circular motion involves constant change in direction, the object exhibits constant acceleration.
How can the acceleration be different from zero in a circular uniform movement?
Ah hah! You're one of those individuals who thinks that "acceleration" means "speeding up". Admit it. It doesn't. 'Acceleration' is any change in the speed or direction of motion. In circular motion, the direction is constantly changing. So, although the speed is constant, that's accelerated motion.
Is uniform circular motion and circular motion is the same?
no, in uniform circular motion the magnitude of your velocity, and therefore your acceleration is constant. in general this does not need to be true. consider this simple experiment, in a children's playground, go to a roundabout. stand on the roundabout and kick once, then wait for your motion to completely stop before kicking again. your motion is still circular, but neither velocity or acceleration is constant.
Why is uniform circular motion considered acceleration?
Acceleration is defined as the change in velocity divided by the time or a = (vf - vi)/t Velocity measures the speed and the direction of an object. In uniform circular motion, the object has the same speed but it is always changing direction and so, by the definition of acceleration, the object is considered accelerating. If this acceleration doesn't exist, the object would move in a straight line according to Newton's laws of motion.
