Y1 Forces

What

Dynamics is the study of forces and it's effect on motion. This aspect of the course introduces the concept of forces and methods you will employ when working with them.

Forces is a huge topic that brings together many areas of Maths. In the first year you will learn the fundamentals of working with forces. This is extended in the second year, so it is important that you become confident with this material.

Students should need to:

Understand the concept of a force and know that it is a vector.
Know and be able to use the 3 Newtons Laws (Most commonly, you will be making use of the second law, F=ma)
Be able to resolve forces effectively in a straight line
Be able be able to use different types of forces such as tension, thrust and gravity
To be able to solve problems where particles are connected, eg Cars and Trailers, Pulleys and Lifts
Be able to confidently apply SUVAT to problems where a force produces an acceleration
Be able to solve problems where force is expressed as a vector

In the second year of A-Level this topic is extended so that forces do not all act in a straight line.

Stretch and Challenge (Madas)

These questions are exam style questions. Some of the questions are more appropriate for the Second Year. As a rule of thumb, ignore questions where there are slopes or forces acting at angles.

It's a great idea to pause the videos on the questions and try the questions before watching the solution.

In these videos, you will see how to apply the laws of forces to real problems

Example Problems

Connected Particles

Many exam questions will involve systems of forces with particles connected together, eg Cars and Trailers, Items hanging over pulleys or objects in lifts. These videos cover all aspects of this.
