Straight Line Motion – How Does it Work? What Is Its Definition? Answer and Explanations: In straight line motion the velocity changes linearly with the angle of rotation. The resultant force is always equal to the force of acceleration times the square of the tangent. B) When the angle of rotation is a right angle then the velocity change is anti-clockwise.
Let’s make this more clear using a drag function, an easy to understand graphical representation of the drag function. We can use a drag function as a straight line function that defines the distance traveled by a rotating body at time t. We can also use the drag function to describe a simultaneous changing in the direction of rotation and the speed of rotation. For example, if the velocity was zero then the magnitude of the angle of attack with respect to the horizontal axis of the vehicle would be zero.
Let’s now assume that we have arbitrarily selected a point on the surface of the earth for our motion reference point. We then want to measure the amount of constant acceleration experienced by the vehicle, as measured from that reference point by a drag function. We will assume that the reference point is moving with respect to the x axis of the spacecraft.
Assume also that the component of velocity applied to the vehicle is the sum of the components of velocity that are experienced by the drag particle as it drifts with respect to the spacecraft. Now, if we plot the corresponding curves on a straight line between the two points on the x axis, then we get a straight line projection of the drag particles onto the spacecraft. The equations of motion for such a system are the same as for the system described in the previous section. The only difference is that the components of the velocity change abruptly and the drag particle experience a variable rate of acceleration along the curved surface.
The equation for such a system can be written more explicitly as follows:
Here, a Taylor rule is used to determine the unit of measure of time to attain a certain acceleration. The first term in the equation, which is the time value of the component of velocity acceleration, is set equal to zero. Next, is the time element of the equation as a function of time. This term describes the relationship between the acceleration of the particle and the time it takes to go from the initial condition to the final condition, which is the instantaneous acceleration at the end of the procedure.
To find the corresponding instantaneous motion values, substitute the terms for the component of acceleration a and b in the equations of motion for the simple-x hull into their algebraic forms. The first term, the instantaneous component of acceleration, can be neglected in this case, as it is the change in velocity with distance that is included in the second term, the displacement velocity. For the purposes of simplicity, the second term is omitted, thus the second term becomes the integral operator on the unit circle tangent to the x-axis. This tangent will be small in comparison to other derivatives, so it is neglected in most cases. It is easily visualized by graphing the displacement velocity as a function of the tangent.
The tangent’s area will depend on the average velocity, which is the normal speed at the end of the procedure when the straight line motion is obtained, and the tangent’s intercept, which is the distance traveled after the velocity has changed. These tangent and velocity terms are plotted as functions of the tangent and average velocity at different times in the tangent’s intercept. By graphing it we can visualize the changes in the slopes of the intercept lines at different times. This plot can be used to determine the slopes of the tangent’s y-axis and to calculate the average velocity and acceleration of the system. This method of calculating the derivative is more accurate than the average velocity and acceleration of a moving system.
