GCSE; WJEC; Distance, speed and acceleration – WJEC Velocity-time graphs of motion. The motion of an object can be predicted by analysing the forces that act on the object. Balanced forces have ...
A steeper slope indicates a greater acceleration. The area under the graph represents the distance travelled by the object. Uniform Motion and Velocity Formula. In uniform motion, an object moves at a constant velocity, meaning it does not accelerate or decelerate. The velocity-time graph for uniform motion is a straight horizontal line.
Learn about motion graphs for your GCSE physics exam. This revision note includes constant speed, changing speed, and the slope of a distance-time graph. ... Step 1: Recall that the gradient of a velocity-time graph gives the acceleration. Calculating the gradient of a slope on a velocity-time graph gives the acceleration for that time period.
In this type of motion graph VELOCITY is plotted along the y-axis against TIME along the x-axis. Look at the VELOCITY-TIME graphs shown below and fill in the gaps. VELOCITY-TIME GRAPHS of a velocity-time graph = ACCELERATION AREA ENCLOSED by a velocity-time graph = DISTANCE TRAVELLED 1. Gradient of graph = Acceleration = m
A curved slope means that the acceleration is changing – the object has non-uniform acceleration. Check carefully whether a graph is a speed-time graph or a distance-time graph. On true speed–time graphs, the speed has only positive values. On velocity–time graphs the velocity can be negative.
In the velocity time graph above, the gradient is a curved line, so the acceleration is constantly changing. As time increases, the gradient decreases (line less steep), this means that the acceleration will decrease. Once the line is horizontal at the end of the graph, the acceleration is zero. When the acceleration is zero, the velocity is ...

This document provides detailed notes on speed, velocity, acceleration, and motion graphs for GCSE Physics. It defines key terms like distance, displacement, speed, velocity, acceleration, and describes how to calculate these quantities using equations of motion. Motion graphs including distance-time and velocity-time graphs are explained. Centripetal force and acceleration are also introduced ...
In the velocity time graph above, the line is straight, so gradient is constant and therefore acceleration is constant or uniform. As the gradient is positive and the velocity is increasing with time, then the object is accelerating.

(b) Calculate the cyclist's acceleration between 5 and 10 seconds. Answer: Part (a) Step 1: Recall that the slope of a velocity-time graph represents the magnitude of acceleration. The slope of a velocity-time graph indicates the magnitude of acceleration. Therefore, the only sections of the graph where the cyclist is accelerating are sections ...

Constructing graphs of an objects motion gives a better idea of the behaviour of the moving object. A distance-time graph is constructed by having the distance as the vertical axis and the time as the horizontal axis. By recording the distance travelled over different intervals of time and plotting these values a distance-time graph can be plotted.
The collection of resources is designed to help you prepare to teach our GCSE Maths to post-16 resit students. They'll help you to reinforce and develop GCSE Maths skills across all curriculum areas. Although originally designed with post-16 teaching in mind, these resources can still be useful in preparing any students for GCSE Maths.
