For motion with a constant acceleration a, from an initial velocity u to a final velocity v, we have the equations in the table below. When the particle is moving with a constant acceleration and its initial velocity is zero. In horizontal direction, the velocity in x-direction will be constant since there is no acceleration. e. In the real world, examples of uniform acceleration include a freely falling object under gravity (ignoring air resistance), where the acceleration due to gravity is approximately (9. Therefore, we can apply the SOLVING FOR DISPLACEMENT (Δx) AND FINAL POSITION (x) FROM AVERAGE VELOCITY WHEN ACCELERATION (a) IS CONSTANT To get our first two new equations, we start with the definition of average velocity: Long distance runners try to maintain constant velocity with very little acceleration or deceleration to conserve energy. a. Use standard gravity, a = 9. r. Jul 23, 2025 · Velocity-Time Graph The curves indicate the velocity-time graph time is plotted along the x-axis and velocity is plotted along the y-axis. The variables include acceleration (a), time (t), displacement (d), final velocity (vf), and initial velocity (vi). t graph) Distinguish between instantaneous and average velocity Define acceleration, including its vector nature Uniform and Non-Uniform Acceleration Uniform Acceleration: When the rate of change of velocity is constant over time, the acceleration is uniform. Free online physics calculators and velocity equations in terms of constant acceleration, time and displacement. Aug 1, 2025 · The Uniformly Accelerated Motion calculator or (kinematic equations calculator) solves motion calculations involving constant acceleration in one dimension, a straight line. Correspondingly, the displacement of a body while uniformly accelerating in a time interval is the mean of the displacement of the body at its initial and final Practice 2C: | 1 | 2 | 3 | 4 | 5 | Go up Displacement with uniform acceleration - by the terrific twins Heather and Lisa, 2005 Aug 1, 2025 · Calculate displacement as a function of initial velocity, acceleration and time using the equation s = ut + (1/2)at^2. For example, acceleration due to gravity on Earth Non-uniform i. time … The concept page Motion with Constant Acceleration looks at the motion of bodies travelling with constant (uniform) acceleration. For example, an object with increasing acceleration Motion of a Bouncing Ball For a bouncing ball, the acceleration due to gravity is always in the same direction (in a uniform This section focusses on kinematics. When For uniform acceleration, (a) remains constant. While finding displacement through the v – t graph, keep the sign under consideration. This page demonstrates the process with 20 sample problems and accompanying Uniformly Accelerated Motion In A Plane Projectile motion is one of the most popular examples of motion in a plane with uniform acceleration. Jul 10, 2025 · This problem exemplifies the application of fundamental kinematic equations to analyze motion with uniform acceleration and constant velocity. This means that the instantaneous acceleration of the body is equal to its average acceleration. By breaking down the motion into distinct phases and applying the appropriate equations, we can accurately calculate the displacement of the body. Aug 1, 2025 · Displacement (s) of an object equals, velocity (u) times time (t), plus ½ times acceleration (a) times time squared (t 2). t is the time over which the acceleration occurs and s is the displacement of the object from its initial position. Curved lines indicate acceleration or deceleration—steeper curves mean faster change in velocity. a constant value. There are three one-dimensional equations of motion for constant acceleration: velocity-time, displacement-time, and velocity-displacement. It emphasizes the usefulness of velocity vs. 8 m/s 2) downwards, or an elevator moving upwards with a constant increase in speed. In circumstances of constant acceleration, these simpler equations of motion are usually referred to as the SUVAT equations, arising from the definitions of kinematic quantities: displacement (s), initial velocity (u), final velocity (v), acceleration (a), and time (t). m) when its trajectory is a straight line and its acceleration is constant and different from 0. 8 m/s2 (ignoring air resistance). It concerns only variables derived from the positions of objects and time. When acceleration is constant, there are three equations that relate displacement to two of the other three quantities we use to describe motion – time, velocity, and acceleration. When the velocity of the particle is constant, or acceleration is zero. In the case of projectile motion, the only acceleration acting on the particle is the acceleration due to gravity (g). . If a body accelerates uniformly, then the value of its acceleration is constant throughout the time interval over which it accelerates. You might guess that the greater the acceleration of, say, a car moving away from a stop sign, the greater the car’s displacement in a given time. Since the acceleration is constant, the displacement-time graph will always be a parabola, the velocity-time graph will always be straight, and the acceleration-time graph will always be horizontal. Displacement During Constant Acceleration When acceleration is constant, there are three equations that relate displacement to two of the other three quantities we use to describe motion – time, velocity, and acceleration. Solve for s, u, a or t; displacement, initial velocity, acceleration or time. If values of three variables are known, then the others can be calculated using the equations.
