Do you need some practice with force diagrams for your introductory (or advanced) physics course? Here are three questions (and the last one is awesome) about the motion of a bike as it is pulled.

Save guides, add subjects and pick up where you left off with your BBC account. Multiple forces act on an object at the same time. The size and direction of these forces determines the movement of the ...

Physics, especially the part about forces and motion, often feels like a maze of confusing concepts and formulas. If you’ve ever stared at a problem about an object moving or a force acting and ...

Augmented Physics: This web-based tool uses machine learning to create interactive physics simulations from textbook diagrams. By semi-automatically extracting content, users can embed dynamic, ...

Multiple forces act on an object at the same time. The size and direction of these forces determines the movement of the object. Show the forces acting on an object in a free body diagram. The arrows ...
