Motion of a Projectile Thrown from an Elevated Platform
The motion of a projectile is controlled by Newton's first law
Here, the acceleration, a, is given by a combination of the initial force applied to the projectile, which propels it forward and up, and gravity, which propels it down until it hits the ground.
Choose initial speed in m/s.
Choose initial height in meters.
Choose initial angle in
Initial Values Entered:
determines the subsequent heights.
Range can be obtained by solving this equation for x with h(x) = 0.
The maximum height attained is most simply obtained by using the kinematic formula:
And we might want to graph the overall trajectory:
Look at the change in the shape of the trajectory, the maximum range, R (how far the projectile goes) and the maximum height, hmax (the height at the top of the parabolic trajectory) as you change the input variables.
