GCSE AQA Physics - P9.2-3 - Velocity - time graphs

New GCSE AQA Physics lesson on ‘Velocity - time graphs’ written in line with new AQA Physics specification.

Starter prompts pupils to discuss what would win a race, a sports car on the road or a car falling from the sky in a mile race. Pupils are then asked to put cars in order acceleration in terms of 0-60 mph.
The difference between speed and velocity is highlighted.
A class activity uses a video car chase for pupils to time the duration of different events which is then used to create a velocity time graph. This allows for the v-t graph to be discussed in terms of what the trends show.

Key v-t graph trends are highlighted and reviewed with how gradients of v-t graphs can give acceleration. Pupils are then tasked to answer questions in relation to the v-t graph from the car chase video.

A quick task requires pupils to match v-t graph trends with d-t graph trends.
The plenary takes a look at a v-t graph for a sky diver to start discussing this area.

Lesson Objectives:

1. Plot a v-t graph.
2. Identify key v-t graph trends.
3. Use the gradient of a v-t graph to calculate the acceleration of an object.
4. Analyse motion of a body using a v-t graph.
