## Equations of Motion

Developing your GCSE knowledge of distance-time and speed-time graphs with your new knowledge of their vector equivalents. In this video I recap a few of the essential things you need to understand about displacement-time and velocity-time graphs, including the significance of the gradient and area. These equations are essential for describing the world around us and the motion of objects. May I introduce the 'suvat' equations! You know the equations of motion, but where do they come from?

This video shows how you can use a simple velocity-time graph to derive four 'suvat' equations. Remember the gradient is equal to the acceleration and the area is equal to the displacement.

How can you solve real problems with the 'suvat' equations? This video shows you a technique that will guarantee you the correct answer every time. Gameboard: Equations of Motion in 1D. Gameboard: Equations of Motion in 1D - constant v. Gameboard: Equations of Motion in 1D - non-zero a.

Gameboard: Equations of Motion in 1D - freefall. What affects how far it takes to stop a vehicle? What is the difference between thinking and braking distance? Watch this to find out a bit more and refresh your knowledge from GCSE.

There are many features on a car that allow it to be safer for the occupants in the event of a collision. A lot of these rely on the principle that if you increase the collision time you reduce the force involved. Don't worry - it's not real! This is just one example of projectile motion and a way that you can solve equations where an object is initially travelling horizontally.

Remember the vertical component of velocity is independent of its horizontal component so it accelerates vertically but not horizontally. Indirect fire provided by the finest regiment in the British Army - the Royal Artillery is the example I used in this video. When you have a projectile fired at at an angle it initially has both horizontal and vertical components of velocity it will follow a parabolic path.

This video shows how you can solve such problems using simple 'suvat' equations.

B4 Trajectories. This is a rather long example with a projectile fired at an angle from a raised platform. I show you how to break up the motion of the projectile into three sections then use suvat for both the horizontal and vertical components of velocity.

As you may know, there are two main equations of motion for uniform acceleration Thus, we have five parameters of motion: initial velocity Vo, final velocity V, acceleration a, time t and displacement S, and two equations.

Obvious conclusion - to use these equations we need three known parameters, and two unknown parameters. As Combinatorics. Combinations, arrangements and permutations tells us, number of combination of 3 from 5 is 10, so, there are ten types of problems at all, each has different set of known parameters.

This calculator allows you to enter any three known parameters and use "-" symbol to denote unknown, and it kindly finds unknown ones.

BTW, by default acceleration has value of gravity g, making it a free fall problem. The Equations for Uniform Acceleration. Initial velocity, Vo. Final velocity, V. Acceleration, a.

Kinematics while loop is infinite, plus other errors. Sam Potter on 19 Mar at Vote 0. Commented: Sam Potter on 21 Mar at I have posted similar things before, so apologies if you have already seen this.

My code is this:. The code is infinite. When I stop it running and plot a graph of t,h it appears that h drastically increases after the first time step. I cannot see why this is the case as the equation for height should mean h decreases as time goes in. Pehaps it is the order I have had to code my variables? I have tried various orders but coudnt get any to work without the error 'Index exceeds array elements 1 '.

Any help would be appricieted. Cancel Copy to Clipboard. Can you show original equations? The initial height h of this part of the question is Sign in to comment.

It's for me. Thank you.Physics can be described as modelling the natural world using mathematics. In the case of moving objects, physics can accurately record and even predict the movement of objects using a set of physical laws and equations.

These equations have helped launch space vehicles and are responsible for the realism of many computer games. The equations of motion relate to the following five quantities:. Of the above u, v, a, and s are vector quantities. Time t is a scalar quantity. If any three of the five quantities are known then the other two may be calculated using the following four equations:. The equations of motion can only be used for an object travelling in a straight line with a constant acceleration.

Analysing motion Equations and graphs Physics can be described as modelling the natural world using mathematics.
