Mechanics
Kinematics
Describe motion: position, velocity, acceleration
5 skills · Complete topic free in the app
Kinematics describes motion without asking what caused it. Practice uniform motion, constant acceleration, free fall, horizontal and angled projectile launches, unit conversion and velocity-time graphs.
Skills in this topic
Uniform Motion
Relate distance, speed, and time at constant velocity, and convert km/h to m/s
Uniform Acceleration
Use the constant-acceleration equations and read velocity-time graphs
Free Fall
Drop and throw objects under gravity: fall time, impact speed, maximum height
Projectile Motion
Split a launch into horizontal and vertical motion to find flight time and range
Launch at an Angle
Resolve a launch velocity into components and find the time to the top, the greatest height and the range
Guides
Understanding Kinematics Intuitively (Motion Without the Cause)
Read motion using position, velocity and acceleration. Work through a velocity-time graph, signed displacement, total distance, free fall and projectile basics.
How to Study Physics Effectively (The Solving Loop)
Physics is not a wall of formulas. See a situation, choose a model, solve, check, and only then open the theory. A practice loop that actually transfers to the next problem.
