In addition, photogates and other accessories are designed to work seamlessly with our projectile launchers. PASCO Advantage: PASCO projectile launchers are designed for repeatable and accurate launches. What seems to be the over-all effect of air resistance on these characteristics of projectile motion: (Answer with: increase, decrease or no effect.) a) Maximum Range: b) Maximum Height: is also known as a drag force, and it always opposes the motion of the object as it tries to pass through the air. In this lab, you will roll a ball down an inclined plane, off the edge of a table, and onto a piece of carbon paper on the floor. Carbon paper and a bullseye can be used to test their hypothesis. The horizontal velocity determines how far the projectile travels during the time it is in the air. Students are asked to use the kinematics equations to predict the horizontal range, given a launch angle and muzzle velocity. as a purely exploratory activity or be used with an activity sheet that guides learners to.

Projectile is fired from the same vertical position as its landing position Comment on this to answer the question of how well the experiment resuits agreed with theoretical predictions, within your measurement systems limitations 6. In unit 6 of physics we will study the motion of projectiles.

Projectile is fired from a higher vertical position than its landing position.

This experiment is conducted in two variations: horizontal range, and use its equation to find the angle of maximum range.

The angle of launch is varied and the horizontal range is measured for each angle. Students are surprised to find that time of flight is not related to muzzle velocity at 0˚ launch angle. The Photogate and Time-of-Flight Accessory are used to measure the time of flight at each muzzle velocity. The kinematics that are associated with the projectile motion are summarized in table 1 below: Table 1: Projectile Motion Kinematics Horizontal Motion ( a x = 0, v x = constant ) Vertical Motion ( a y = g =− 9.8 m / s 2 ) v x = v y 0 v y = v y 0 − ¿ x = x 0 + v x 0 ' y = y 0 + v y 0 t − ( 1 2 ) gt 2 v 0 2 = v y 0 2 − 2 g ( y − y 0 ) Based on the above kinematic equation, we have v x 0 = v 0 cos θ Equation 1a v y 0 = v 0 sin θ Equation 1b Since θisgiven bythe angle of inclination ,the following twocases exist : Case 1: θ = 0 °, x 0 = y 0 = 0 v x 0 = v 0 Equation 2a v y 0 = 0 Equation 2b t = √ y 0.5 g = √ y 4.Students fire the projectile at three different velocities from the same height. INTRODUCTION A projectile motion is always experienced when an object is moving through air and is subject to the influence of the acceleration due to gravity. 6.There is no definite correlationbetween length of travel along the plane and the average horizontalvelocity. The first case was considered in order to evaluate the initial velocity, the second case was to find the angle of inclination by first setting the launcher at an angle of 40 degrees and the third case where the angle was determined by setting the launcher at 0.5 m (theoretical) range. Conclusions 5.The greater the height ofrelease along the plane is, thegreater the average horizontal velocity of the projectile is(because potential energy turnsinto kinetic energy as the ballrolls down the plane). Helpful Hints: Estimate the ball’s landing location by looking at the landing spot for the center of the bottom of the ball. By use a ball launcher to shot and simulate the projectile motion, three cases were utilized to examine the projectile motion while applying the kinematic equations of projectile motion. In part 1 of this lab, a marble will accelerate down a ramp which will cause it to have horizontal velocity, which will be. Objective: In this activity, you will be investigating the relationships between some of the diferent variables involved in projectile motion.
