Physics Linear Motion Formulas ~ Consider a body moving in a straight line from an initial velocity u to a final velocity v u v 0 within a time t as represented on the graph below. In physics just as you can use formulas to calculate linear velocity acceleration displacement and motion you can also use equivalent formulas for angular rotational movement. Here s a list of some important physics formulas and equations to keep on hand arranged by topic so you don t have to go searching. Linear motion is the simplest kind of one dimensional motion. When an object undergoes linear motion we always model the motion of the object over straight segments separately. More specifically the equations of motion describe the behaviour of a physical system as a set of mathematical functions in terms of dynamic variables. S v 0 t at 2 2 velocity position. Over one such segment the acceleration vector will be co linear with the displacement vector of the object parallel or anti parallel note that the acceleration can change direction as it would from a spring force but will. Average velocity speed of a moving object can be calculated as. Non uniform linear motion with variable velocity or non zero acceleration. Indeed lately has been sought by users around us, perhaps one of you personally. Individuals are now accustomed to using the net in gadgets to view video and image information for inspiration, and according to the title of this article I will talk about about Physics Linear Motion Formulas. This inertial frame of reference can be described as a 3 dimensional coordinate system that is either stationary or in uniform linear motion. You can think of the angle theta in rotational motion just as you think of the displacement s in linear motion. As newton s first law of motion suggests an object will either be in rest or continue to move in a straight line with a uniform velocity unless and until an external force is applied to it. Newton s laws of motion are for the motion of massive bodies in a given inertial reference frame. Here s a list of some important physics formulas and equations to keep on hand arranged by topic so you don t have to go searching. The change in position s is called the displacement or distance depending on circumstances and some people prefer writing the second equation of motion like this. Acceleration a v u t. Vertical the speed that the object loses on the way up it gains on the way down projectile motion. The first two equations of motion each describe one kinematic variable as a function of time. The general linear wave equation in 3d is.
As newton s first law of motion suggests an object will either be in rest or continue to move in a straight line with a uniform velocity unless and until an external force is applied to it. Non uniform linear motion with variable velocity or non zero acceleration. Vertical and horizontal vertical velocity changes because of gravity whereas horizontal velocity remains constant any angle will travel exactly the same distance as its complimentary angle v i.
Physics is filled with equations and formulas that deal with angular motion carnot engines fluids forces moments of inertia linear motion simple harmonic motion thermodynamics and work and energy.
Linear motion is the simplest kind of one dimensional motion. The first two equations of motion each describe one kinematic variable as a function of time. In physics just as you can use formulas to calculate linear velocity acceleration displacement and motion you can also use equivalent formulas for angular rotational movement. In physics equations of motion are equations that describe the behavior of a physical system in terms of its motion as a function of time.
