To really understand torque for your AS-Level Physics exams, here are some key points to focus on:
What is Torque?
Torque (which we often write as τ) is how much twist or rotation force you put on something. You can think of it like this: τ = r × F. Here, 'r' is the distance from where something spins (the pivot point) to where you’re pushing, and 'F' is the amount of force you're using.
Why is Torque Important?
Torque helps keep things steady and stable. For example, when you open a door, you need a certain amount of torque. If you push the door with a force of 10 N (newtons) at a distance of 1.5 m (meters) from the hinge, you create a torque of 15 Nm (newton-metres) to open it.
Practice Makes Perfect
Keep practicing problems that involve torque and moments. Try to solve at least 20 different problems. This will help you really get the hang of it.
Use Visuals
Diagrams can help a lot! Draw pictures to show forces, distances, and pivot points. This makes it easier to see how torque affects things in the real world.
