Problem: how does the law of inertia affect the physical world
Hypothesis: the bigger ball will go farther then the small ball,because the bigger ball has more mass than the small ball, so it will have more speed going down the ramp.
Cv: hit of force on ball, surface, inclined plane, and the angle and distance of inclined plane
Iv: Size of ball getting hit
Dv: Distance the hit ball goes
Materials: ruler, inclined plane, marker, A small and light ball, and A big ball that has some weight
Procedure:
Gather Materials
Place one end of the inclined plane on a flat smooth surface and raise the other end up ten centimeters
Place the marker or dot on the incline plane to show where the ball has to go.
Place one of the balls on the smooth flat surface at the dot or marker of the ramp so that it is always equal
Position the ruler so that the 0 is lined at the side
Record the distance that the bottom car rolled
Repeat steps 2-3 more times
Repeat steps for the other ball
Record new results
Clean up.

Observations:When the greater mass and bigger ball hit it went farther than the smaller, because of the ball's mass was greater.

Conclusion: The balls rolled different distances because the lighter ball didn't have as much force as the greater mass ball. This is proof that Newtons First Law is true since the balls had to have a different amount of force to move the same ball different distances. The large ball moved the ball the farthest because it had the most force and the lesser mass ball moved the car less because it did not have as much force. Some probles I had were that the ball did not go straight all the time so I used the tape measure that could curve and measure it that way.
