Projectiles Launched Horizontally

Physics

Learning Made Easy

Learners investigate the effects of initial speed and height on range and duration of projectile flight of an object that is launched horizontally.

Now You Know

After completing this tutorial, you will be able to complete the following:

Describe the starting altitude as directly proportional to the maximum vertical displacement for a projectile that was launched horizontally.
Describe that the initial horizontal velocity has no effect on the duration of flight for a projectile that was launched horizontally.
Explain that the vertical motion of a projectile that was launched horizontally is the same as that of an object in free fall.
Describe the starting altitude as directly proportional to the final horizontal displacement for a projectile that was launched horizontally.
Describe the initial horizontal velocity as directly proportional to the final horizontal displacement for a projectile that was launched horizontally.

Everything You'll Have Covered

Graphing projectile motion can deepen conceptual and mathematical understanding. Projectiles are examples of two-dimensional motion, with horizontal and vertical components and, therefore, x-axis components and y-axis components, respectively. Studying projectile motion may involve investigating the relationships between gravitational acceleration, initial velocity, and angle of launch. A projectile launched at an angle follows a parabolic trajectory. Gravity and air resistance affects the trajectory of these projectiles. This Activity Object focuses on projectiles launched horizontally, such as a ball rolling off a table or a car driving off a cliff.
