2D motion
Two dimensional motion covers projectile motion, circular motion, and Newtons law of universal gravitation.
Projectile Motion
- Projectile
- An object where the only force acting on it is gravity
- Air resistance is negligible
- X and Y motion is independent

Universal Circular Motion
The motion of an object traveling in a circular path

- Centripetal Acceleration
- The acceleration of an object traveling in a circle will point towards the center of the circle and this is the centripetal acceleration
- Instantaneous velocity
- The instantaneous velocity is perpendicular to the radius of the circle it is traveling at any time.
Universal Law of Gravitation
Describes to Interaction between 2 objects and the gravity forces exerted on them.
Force of Gravity = Universal Gravitational Constant (6.673×10-11 N m^2 kg^-2) *(Mass of Object 1 (Kg) * Mass of Object 2 (Kg) / (distance between center of the objects (m))^2)
