Why is the motion of an athlete moving along the circular path an accerlated motion?
Because 'accelerated motion' means any change in speed orany change in directionaway from a straight line. So motion on a circular path is always accelerated motion.
Can an object be accelerated if it is moving with constant speed?
Yes. The simplest such case is when the object is moving along a circle.
How does the direction of the acceleration along determine if the object is speeding up or slowing down?
Take the component of the acceleration along the direction the object is moving. If this component is positive (the acceleration vector, or the relevant component, points in the same direction as the movement), then the object is speeding up.
Why do you need a force to keep a body moving uniformly along a circular path?
Because even though the speed of an object moving in a circular path is constant, its velocity is not. And according to Newton's first law a change of velocity is evidence of a force. The difference is that speed is just the absolute value of velocity, it just says how many units of distance an object can travel in one unit of time. Velocity on the other hand also contains information about the direction of an object (you can regard it as 3 numbers specifying the speed in x, y and z directions). And the direction of motion for a body moving in a circular path DOES change even though its speed does not, therefore a force is needed. (The force decreases the speed in one direction and increases it in another).
How does adding and removing of force affect a moving object and an object at rest?
For an object in motion, a force applied in the direction of the movement of the object would propel it further along that direction. The force should be equal or more than the momentum of the object. If a force in applied against the moving object in a direction opposite to the movement of the object, the velocity of the moving object is hampered. How much this decrease in velocity would occur would depend on the amount of the opposing force. If a sufficiently large force in an opposing direction is applied, it can even stop the object. If the force is not along or opposite the movement of the object, the force can change the direction of the object. If the force that was causing the movement of the object is removed, the object slows down, until it finally stops. For an object at rest, a sufficient amount of force can set the object in motion.
Is uniform circular motion is accelerated motion?
if an object moves along a circular path, the only change in its velocity is due to the change in the direction of the motion. The motion of the object moving along the circular path is, which is a uniform circular motion, is therefore an accelerated motion:):):):/
Why uniform circular motion is called accelerated motion?
if an object moves along a circular path, the only change in its velocity is due to the change in the direction of the motion. The motion of the object moving along the circular path is, which is a uniform circular motion, is therefore an accelerated motion:):):):/
What is circular motion?
Circular Motion -a motion along a circular path or the motion of an object in a circular Example -blades of a ceiling fan when the fan is switched on. or The motion of body along the circular path is called circular motion

What does stay in orbit mean?
It means that an object remains in a stable orbit around a central object. For example the Earth stays in a stable near-circular orbit around the Sun although it is continuously moving at around 18 miles per second in a direction that is along the ecliptic and at right angles (approximately) to the direction of the Sun.
What direction does friction act in to an object's direction of motion?
Friction will always act in the direction opposite of the relativistic motion of two objects. If object A is moving to the right on object B, then object A will experience the friction to the left. However, object B will be moving to the left on object A and will therefore experience the friction acting towards the right.

When an object is traveling in a circular path around another object?
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
What is meant by centripetal acceleration is perpendicular to velocity?
As an object goes round in a circular path, then its velocity will along the tangent at that instant. But centripetal acceleration is normal to that tangent and so along the radius of curvature. As acceleration is perpendicular to the velocity, the direction aspect is ever changing and so the object goes round the circular path.
