12 Questions
What force causes the objects to move in a circular path instead of a straight line?
Centripetal force
Is the motion of the Earth around the Sun considered uniform circular motion?
No, the motion is non-uniform and elliptical
What is the time of revolution of the wooden block on the rotating disc?
The time of revolution is constant
What is the shape of the path of the wooden block on the rotating disc?
Circle
What is the speed of the wooden block on the rotating disc?
The speed is constant
What is the main concept that Newton used to explain the motion of the Moon?
Uniform circular motion
What is the defining characteristic of uniform circular motion?
The body moves with a constant speed in a circular path
Does the velocity of a body in uniform circular motion change?
Yes, the velocity changes in direction but not in magnitude
What is the direction of the acceleration of a body in uniform circular motion?
Perpendicular to the velocity vector
What is the formula for the magnitude of the acceleration of a body in uniform circular motion?
$a = v^2 / R$
How can the change in velocity of a body in uniform circular motion be represented?
Both a and b
What is the relationship between the time period $T$ and the radius $R$ of the circular path in uniform circular motion?
$T = 2 ext{\pi} R / v$
