Clay Shooting
Projectile motion Let’s consider the movement of throwing an object horizontally. Assuming no air resistance, there is no horizontal force, so no change in horizontal speed. In other words, it’s constant velocity…

Gear
Let’s combine various gears by dragging the screen. How can I combine to speed up? How can I combine to slow it down?
Projectile Motion
What about x-component of velocity during projectile motion? What about y-component of velocity during projectile motion? What direction does the object’s motion change? (Horizontal direction or vertical direction)
Uniformly Accelerated Motion
Drop the object free by clicking on the screen. What is the relationship between the time-distance graph and the time-velocity graph?
