In simple harmonic motion, displacement, velocity and acceleration vary sinusoidally with time, but with different phases.

More details | Watch now#### Circular motion

Uniform circular motion: angular displacement and velocity are introduced and centripetal acceleration is determined.

More details | Watch now#### Projectile motion

Motion with uniform acceleration, such as in a uniform gravitational (or electric) field is projectile motion, analysed here with examples.

More details | Watch now#### Motion with constant acceleration (kinematics)

Kinematics quantifies motion without explaining the causes of it. Here we study accelerations that are zero, positive or negative.
