What is the purpose of the projectile motion lab?
The purpose of this experiment is to predict and verify the range and the time-of-flight of a projectile launched at an angle. To predict the range of the projectile when it is shot off a table at some angle above the horizontal, it is necessary first to determine the initial speed (muzzle velocity) of the ball.
How does an angle affect projectile in motion?
Higher launch angles have higher maximum height Since steeper launch angles have a larger vertical velocity component, increasing the launch angle increases the maximum height.
How does the launch angle affect the range of a projectile experiment?
The highest point in the trajectory occurs at the midpoint of the path. This highest point increases as the angle increases. At a 75° launch angle, the maximum height is approximately 76 meters. However, a further increase in launch angle beyond this 75° angle will increase the peak height even more.
What is the importance of projectile motion in sports?
Understanding how projectile motion works is very beneficial in determining how to best propel an object. For the javelin throw, being able to calculate the different variables helps the athlete to develop a better technique for them personally in order to throw the longest distance.
What are the characteristics of projectile motion?
Objects experiencing projectile motion have a constant velocity in the horizontal direction, and a constantly changing velocity in the vertical direction. The trajectory resulting from this combination always has the shape of a parabola.
How does the angle of projection affect the range and maximum height of a projectile?
Generally, when the projectile velocity and the angle of projection are held constant, the higher the projection height, the longer the flight time. Hence, if flight time is longer then distance is greater.
What factors affect the distance a projectile travels and how?
Factors affecting the flight path of a Projectile are:
- Gravity.
- Air Resistance.
- Speed of Release.
- Angle of Release.
- Height of Release.
- Spin.
What are the important application of projectile motion?
The applications of projectile motion in physics and engineering are numerous. Some examples include meteors as they enter Earth’s atmosphere, fireworks, and the motion of any ball in sports. Such objects are called projectiles and their path is called a trajectory.
What have you learned about projectile motion?
A projectile motion involves two components of motion – vertical and horizontal. Characteristically, motion in one direction is independent of motion in another direction. Projectile motion is a special case of two dimensional motion with constant acceleration.
What can you conclude about the characteristics of the projectile trajectory?
What is angle of projectile?
One of the key components of projectile motion and the trajectory that it follows is the initial launch angle . This angle can be anywhere from 0 to 90 degrees. The angle at which the object is launched dictates the range, height, and time of flight it will experience while in projectile motion .
What is the conclusion of projectile motion?
Projectile motion is concluded when a projectile stops moving. Assuming nothing gets in the way, that conclusion is reached when the projectile comes to rest on the ground. On Earth, the motion of any projectile has both a horizontal component and a vertical component.
What is the projectile motion lab?
This will teach the concepts of projectile motion for objects that start from horizontal and objects that start at angles. Familiarity with kinematic equations will be increased through there repeated use in this lab.
What are the possible sources of error in projectile motion measurements?
These measurements had many possible sources of error including air resistance and firing position. This lab increased understanding of projectile motion. Projectile motion occurs when an object in a two dimensional plane experiences motion only due to gravity.
What are the parameters of a launched projectile?
Objective: In this lab we will compare different parameters of a launched projectile. This includes time of flight, initial velocity, initial vertical velocity, initial horizontal velocity, range, time of max height. All these data points are collected for 30°, 40°, 45°, 50°, 60°, 70°.
