Since motion is based on specific mathematical forces, they can be calculated precisely. For example, when you drop an object near Earth's surface, the force of gravity will accelerate it downward at about 10 meters / second2. This means for every second an object is falling, (ignoring air resistance), its speed will increase by ~10 m/s.
You drop an item from high up. How fast will it be going after 2.2 seconds (in m/s)?
