Rectilinear Motion

what is rectilinear motion in physics

The study of motion and of physical. What is its stopping distance for this speed? Depending upon the path taken by the particle the motion can be of different types like projectile motion, rectilinear motion, rotational motion etc. Please type or write your answers on a separate sheet of paper, not squished in the spaces on these pages. We need to find a. Motion of the particle may be expressed in the form of a function, e. Thus we have u, a and t - all in the correct units.

Rest and Motion What is Motion? Kinematics of Particles Lecture Notes: J. Solution A sketch of his motion is shown in figure. When measuring position, the path typically follows this axis, as a function of time or other variable in the Y-axis. One common example involves shooting a projectile up into the air. We start our study of kinematics by first discussing in this chapter the motion of a particle. Velocity can vary by a change in magnitude, by a change in direction, or both. Given the position of the particles, x t , we can calculate the displacement, velocity, and acceleration.

But the direction of acceleration is generally not tangent to the curve. Referring to graph on the right the difference between the two lines is that one line is at a faster speed than the other in the same amount of time. The speedometer in an automobile indicates the instantaneous speed of the automobile. Kinetics is used to predict the motion caused by given forces or to determine the forces required to produce a given motion. A body in motion may be said to have equal to the product of its mass and its velocity. The curved path can be in two dimensions in a plane , or in three dimensions. Answer: Step 1 : We are given the quantities u, s and t — all in the correct units.

FHSST Physics/Rectilinear Motion/Definition

what is rectilinear motion in physics

The first part of inertia states a stationary object cannot move unless something exerts a force on that object. It is equal to the ratio of total displacement and time interval, but with one qualification that time interval is extremely infinitesimally small. At a later time t 2, let this particle be at point B, described by position vector. If it is braking the direction of acceleration is opposite to the direction of its motion, i. The results show that the measurement system, consisting of two separated sources of fluctuations moving in a near-Earth space, can detect its own motion in form of a local time effect, or in other words, we can determine uniform and rectilinear motion of an isolated system on the basis of measurements made inside the system.

To illustrate this imagine a train heading east. Acceleration, velocity, displacement, and angular velocity belong to this category. A convenient way to fix a frame of reference is to choose an origin and three mutually perpendicular axes labelled as x, y and z axes. The magnitude of average velocity and average speed may not be equal, but the magnitude of instantaneous velocity is always equal to instantaneous speed. For instance, a ball on the pitch can only move if you kick it.

Rest and Motion

It is usually reported in meters per second. Easily unsubscribe at any time. The motion is described for objects not influenced by an external force, which usually includes. Without an applied force, bodies tend to resist acceleration and to stay at rest if they are at rest or, when moving in a straight line, to continue moving in a straight line. Objective: To explore the acceleration and force of an object that travels a circular path at constant speed. When a body moves uniformly along the circle, then: a its velocity changes but speed remains the same b its speed changes but velocity remains the same c both speed and velocity changes d both speed and velocity remains same 4. Similarly, if two cars are going side by side with same speed then with respect to each other they are in a state of rest, but with respect to trees and persons on the road they are in a state of motion.

The motion of a single wheel of the car is not rectilinear, although the motion of the center of mass of the wheel may be essentially so. Distance is a scalar quantity which has magnitude only. The motion will be in the direction of the force. The second law of motion describes force, and how it is directly proportional to acceleration. Note that the circumferential direction is perpendicular to the radial direction.

Thus, in general, magnitude of displacement is not equal to the distance travelled. If a body starts from rest, what can be said about the acceleration of body? Acting in the opposite direction of the original velocity, the speed will be decreased, rather than increased. This law allows people to determine the mass, acceleration, or force involved in a motion while only knowing two variables. This behavior of objects is called inertia. Average Speed and Average Velocity The average speed in a time interval is defined as the total distance travelled by the particle divided by the time interval. To find the required quantities, we need the total time interval. Calculus is generally used for determining functions such as velocity by using time and position values in an equation.
