Instructions : Launch the projectile at different initial velocities, angles and heights to observe their different paths.

What is Motion?

Motion is the change in position of an object over time. There are two main components of motion - magnitude and direction. The projectile is in motion after it's launched from the cannon.

Speed is the distance traveled per unit time. Velocity is speed with direction. If you were driving at 50 km/h towards North, your speed would be 50 km/h whereas your velocity would be 50 km/h due North.

What is Gravity?

Gravity is a natural force of attraction between two objects having some mass.
The region around an object where its force of gravity can be felt is called its gravitational field,
and its intensity is expressed as the gravitational acceleration. Earth's gravitational acceleration is 9.8 m/s^{2}.

What is Projectile Motion?

It is a type of motion experienced by a projectile when launched. It causes the projectile to move along a parabolic path. The vertical component of the projectile is given by the gravitational acceleration and the horizontal component is given by its initial velocity. The angle to the horizontal at which the projectile is launched also influences the horizontal and vertical components.

What is a Parabola?

A parabola is a U-shaped curve which is also the graph of a quadratic polynomial, y = ax^{2} + b, where a and b are some constants.
