What is the purpose of projectile motion experiment?
What is the purpose of projectile motion experiment?
The purpose of this experiment is to measure the initial velocity of a ball that is fired from a projectile launcher (spring gun) by measuring its horizontal and vertical displacement. You will use the equations of motion for projectile motion to calculate the initial velocity.
What makes a catapult launch further?
A Sturdy Base Makes a Big Difference Weigh down the base of your catapult to prevent it from moving around during the launch. Any movement in the base can reduce the amount of power behind the launch and can also compromise the trajectory.
How does a catapult work Physics for kids?
The catapult science basically involves some physics and engineering skills to hurl a projectile without the use of an explosive. It works mainly by using potential and kinetic energy stored in the rubber bands. Potential energy is the store energy where as the kinetic energy is the energy in motion.
What kind of projectiles can a catapult launch?
From medieval times to the present day, engineers have designed catapults to launch into the air projectiles as varied as stones and airplanes.
What are the components of a catapult experiment?
Our catapults will consist of a base, a plastic spoon, and a duct-tape sling. We will use a plastic golf ball as the projectile. For the first part of the experiment, you will need to calibrate the catapult. This will involve determining experimentally the relationship between launch angle and projectile travel distance.
What does launch into learning mean for catapults?
This means the projectile will go faster and farther. Following the lesson, challenge students to complete the associated activity Right on Target: Catapult Game to build accurate and precise catapults using simple materials. (Optional: show the attached Engineering Fun!
How does air resistance affect a catapult launch?
Air resistance accelerates the ball in the opposite direction of travel. In order to make a catapult useful, we will want to be able to predict where a projectile will land after launch. To do this, we need to calibrate the catapult. Calibration will take into account all accelerations (including air resistance).
