Torque

Torque is the rotational equivalent of linear force in physics and mechanics. Based on the course of study, it is also known as the moment of force, rotational force, or turning effect.

Question

An object is undergoing simple harmonic motion along the x-axis. Its position is described as a function of time by x(t) = 2.8 cos(3.1t – 1.4), where x is in meters, the time, t, is in seconds, and the argument of the cosine is in radians.

Find the amplitude of the simple harmonic motion in meters.

What is the value of the angular velocity in radians per second.

Determine the position of the object in meters and the objects velocity in meters per secondd when the time=0.

Definition Definition Rate of change of angular displacement. Angular velocity indicates how fast an object is rotating. It is a vector quantity and has both magnitude and direction. The magnitude of angular velocity is represented by the length of the vector and the direction of angular velocity is represented by the right-hand thumb rule. It is generally represented by ω.

Hi, I am in physics I and they have the question of what is the angular displacement between 5s and 15s. At 15s, there is an angle of 50. But at 15 seconds, the angle is between 50 to 75. I have attached the picture of the graph. I understand that the angular displacement requires subtracting the final and initial angle and time from each other. But I really need to know which the angle is for 15s.
