ROTATIONAL MOTION

Question 1

involves an object moving from one point to another in a straight line.

Answer 1

Linear motion

Question 2

can be defined as the motion of an object around a circular path, in a fixed axis.

Answer 2

Rotational motion

Question 3

when an object move along the circumference of a circle.

Answer 3

Circular motion

Question 4

analogous rotational quantities;

Answer 4

Angular Position
Angular Velocity
Angular Acceleration

Question 5

refers to the orientation of an object in relation to a fixed reference point, usually measured in radians, degrees, or revolutions. It’s a measure of how far an object has rotated around a specific axis from a defined zero or starting position.

Answer 5

Angular Position

Question 6

Before going into the details of angular motion we should make a distinction between positive and negative rotation.

Answer 6

Angular Position

Question 7

clockwise rotation is

Answer 7

negative

Question 8

counter-clockwise rotation

Answer 8

positive

Question 9

denoted by ω. is a measure of how rapidly the angle θ is changing with time.

ω is usually measured in units of radians per second (rad/s)

Answer 9

angular velocity

Question 10

we can define angular velocity as

Answer 10

ω = ∆θ/∆t

Question 11

denoted by α The average angular acceleration during a time interval ∆t is related to changes in ω by;

Answer 11

Angular Acceleration

Question 12

The time required to complete one revolution is called the ____________, or the time it takes for an object to complete one full revolution denoted by T. It is related to the angular velocity ω (rad/s)

Answer 12

period of the motion

Question 13

period of the motion formula

Answer 13

T = 2π/ω
