1. Gravity

4. With no air resistance why do the elephant and mouse fall together?

6. Look at the forces

7. Regardless of mass, acceleration due to gravity is always the same on Earth. 9.8 m/s 2 Every second an object falls it’s velocity increases by 9.8 m/s NO AIR RESISTANCE

9. As an object falls with air resistance the force of air increases as the object increases speed. WHEN BALANCED = TERMINAL VELOCITY
