**Aims…**

**1.3 ****plot** and **interpret** **distance–time** graphs

**1.7 ****plot** and **interpret velocity–time **graphs

**1.8** determine **acceleration** from the **gradient** of a velocity–time graph

**1.9** determine the **distance travelled **from the **area** between a **velocity–time graph **and the **time axis.**

**1.4** **know** and **use** the relationship between average speed, distance moved and time: **average speed = distance moved/time taken**

**1.5 ****practical: **investigate the motion of everyday objects such as toy cars or tennis balls.

**1.6** **know** and use the relationship between **acceleration**, **velocity** and **time**:

**acceleration = change in velocity/time taken OR ***a*** = (***v*** – ***u***)/***t*

**1.10** **use** the relationship between **final speed**, **initial speed, acceleration **and **distance moved:**

**(final speed)**^{2}** = (initial speed)**^{2}** + (2 x acceleration x distance moved) OR ****v**^{2}=u^{2 }+ (2as)

Tangents to a Curve - GCSE Physics

This video introduces tangents to a curve. This is slightly more complicated than calculating the gradient of a straight line. It involves the same method of calculating the gradient of a straight line but with an extra step.

Sometimes you need to work out the slope at a particular point on a curve:

- Carefully draw a straight line with a ruler that just touches the curve

- Work out the gradient of this straight line in the usual way

This is a quick video walkthrough of an Edexcel exam question. It is designed so you can look at questions which relate to questions from specific parts of the course.

It is taken from a real paper and I have used a real mark scheme which I have adapted for on-screen use. If you listen carefully it will give you a really good idea of what an examiner is looking for.
