Reducing pressure has opposite effect, gasses expand and so reaction is less vigorous. http://staff.um.edu.mt/jgri1/teaching/che2372/notes/10/10_16.gif (Collision photo) http://www.roadcover.co.za/wp-content/uploads/2011/09/car-crash-wallpapers_5294_1024x768.jpg (another collision photo) Hypothesis For a hypothesis a plastic cart was placed on a ramp which lead down to tracks. Then a meter ruler was placed next to the track , and a block was placed on the track. Then marked where the block remained using a marker, then released the cart to hit the block causing a collision. Then a cylinder was placed after writing down the results(On a numerical table) of how far the block was pushed from the marked spot.
2. "F = ma: the net force on an object is equal to the mass of the object multiplied by its acceleration." 3. "To every action there is an equal and opposite reaction." To prove the 1st law, you can see that the air released from the balloon disturbs the state of rest of the car and makes it move.
