Also, after getting the data, Tracker Video fit a function for me so that I have: The slope of the x-t graph (this is the x-velocity) The parameters of the 2 nd order polynomial that fits the y-t ...

Horizontal Projectile Motion As the name suggests, horizontal motion occurs when the object is thrown horizontally, meaning it starts with zero vertical velocity.

The horizontal and vertical motion of the object are independent (except for the total time). The vertical acceleration is constant (at –9.8 m/s 2 ). The horizontal velocity is constant.

But here's the bit that justifies Dawson's explanation of projectile motion. Basically, a projectile like a golf ball has two velocity components, a horizontal one and a vertical one, as Martin ...

Velocity measurement begins with the passage of the projectile over Q1. The resulting partial occlusion of Q1's view generates a negative pulse at A1's noninverting input of about 500 µV for ...
