For simple harmonic motion (SHM) of a particle, acceleration (a) is given by the relation:
\(a\) =\(– \omega^2 \times \omega \rightarrow angular \,frequency\) ....(i)
\(t\) = \(0.3 \,s\)
In this time interval, x is negative. Thus, the slope of the x - t plot will also be negative.Therefore, both position and velocity are negative. However, using equation (i), acceleration of the particle will be positive.
\(t\) = \(1.2 \,s\)
In this time interval, x is positive. Thus, the slope of the x - t plot will also be positive. Therefore, both position and velocity are positive. However, using equation (i) acceleration of the particle comes to be negative.
\(t\) = \(– 1.2 \,s\)
In this time interval, x is negative. Thus, the slope of the x - t plot will also be negative. Since both x and t are negative, the velocity comes to be positive. From equation (i), it can be inferred that the acceleration of the particle will be positive.
The motion in a straight line is an object changes its position with respect to its surroundings with time, then it is called in motion. It is a change in the position of an object over time. It is nothing but linear motion.
Linear motion is also known as the Rectilinear Motion which are of two types:
