Practice
Pick a topic and work until it is automatic. Every problem has new numbers and a full worked solution that uses the equations from the course framework.

Unit 1: Kinematics
- Topic 1.2, 1.3Motion with constant accelerationAverage velocity and acceleration, then the three constant-acceleration equations: final speed, displacement, stopping distance and free fall.
- Topic 1.5Projectile motionSplit a launch into horizontal and vertical motion: time of flight, maximum height, range and a ball rolling off a table.
Unit 2: Force and Translational Dynamics
- Topic 2.5, 2.7Newton’s second law, friction and rampsNet force and acceleration on level floors, ramps and a cart pulled by a hanging block, with kinetic and static friction.
- Topic 2.9Circular motionCentripetal acceleration, speed from the period, the force a string supplies, the slowest speed at the top of a loop and the fastest on a flat curve.
Unit 3: Work, Energy, and Power
- Topic 3.1, 3.2, 3.3, 3.4Work and energyKinetic and potential energy, work by a force at an angle, the work-energy theorem, and conservation of energy for falls and springs.
- Topic 3.5PowerAverage power for lifting at constant speed, the time a motor needs for a job, and instantaneous power from force and velocity.
Unit 4: Linear Momentum
Unit 5: Torque and Rotational Dynamics
- Topic 5.1, 5.2Rotational kinematicsAngular velocity, angular displacement and revolutions under constant angular acceleration, and the linear speed and distance of a point on the rim.
