Topic 1: Motion and Relativity
Module overview β- Why is the total momentum of an isolated system the same before and after a collision, even when kinetic energy is lost?Apply conservation of momentum to elastic and inelastic collisions in one dimension, and distinguish them using kinetic energy.8 min answer β
- How do Newton's three laws relate the forces on an object to its motion?Apply Newton's three laws of motion, drawing free-body diagrams and resolving forces to determine the acceleration of objects and the forces in interacting systems.8 min answer β
- What does Einstein's equation E = mc^2 tell us about the relationship between mass and energy?Apply mass-energy equivalence to rest energy and to the mass defect and energy release in nuclear processes.8 min answer β
- How does the impulse of a force change the momentum of an object?Relate impulse to the change in momentum of an object using , and interpret force-time graphs.7 min answer β
- How does the gravitational attraction between two masses depend on their masses and separation?Apply Newton's law of universal gravitation and the concept of gravitational field strength to interactions between masses.8 min answer β
- What determines the speed and period of a satellite, and why does the same gravitational force produce a stable orbit?Analyse the orbital motion of satellites by equating gravitational force to the centripetal force requirement, deriving orbital speed and period.8 min answer β
- How can the motion of a projectile be predicted by treating its horizontal and vertical motions independently?Resolve projectile motion into independent horizontal (constant velocity) and vertical (constant acceleration) components to predict range, time of flight and maximum height.8 min answer β
- How do Einstein's two postulates lead to the conclusion that time itself depends on relative motion?State Einstein's postulates of special relativity and apply time dilation and length contraction to objects moving at relativistic speeds.9 min answer β
- Why does an object moving at constant speed in a circle still accelerate, and what force keeps it on the circular path?Describe uniform circular motion using centripetal acceleration and force, relating them to speed, radius and period.8 min answer β
- How do work, kinetic energy and power describe the transfer and rate of transfer of energy in mechanical systems?Calculate work done by a force, relate net work to change in kinetic energy via the work-energy theorem, and define power as the rate of doing work.8 min answer β
