Kaneisha Winch's 'Projectile Motion'
Projectile Motion
By Kaneisha Winch
Aim: To investigate whether there is a relationship between the horizontal velocity and vertical velocity by using a 7.5 cm baseball in projectile motion.
Hypothesis: There is no relationship between the horizontal and vertical velocity. No matter how fast the horizontal velocity, the vertical velocity will remain the same. This has no relation to the size or mass of the ball.
Materials:
• a baseball with a diameter of approx. 7.5 cm
• a tape measurer
• a surface with a height of 75cm from the ground
Background:
Contrary to popular belief many experiment show that if you throw an object or drop the same object they will both hit the ground at the same time. One example of these types of experiments is: Imagine you have a loaded nerf gun in one hand, and a nerf dart in the other. You hold out your hands at the same level, and then, at the same time, you fire the dart in the nerf gun and drop the dart from your other hand. Both darts will hit the ground at the same time even though one is moving horizontally while the other one is just falling. (science classroom, 2017). Does this mean the horizontal velocity is independent to the horizontal velocity? Well this experiment will test that theory. …show more content…
2) Measure a height at which the baseball will be dropped. (The ball in this experiment was dropped from a height of 75cm)
3) Push the ball off the table several times, using different amounts of force (by increasing the force applied to the ball, the horizontal force is increased).
4) Ensure you use the iPad to film each trial, recording the movement of the ball and where it lands.
