What is the purpose of projectile motion lab?
The purpose of this lab is to study the properties of projectile motion. From the motion of a steel ball projected horizontally, the initial velocity of the ball can be determined from the measured range.
What is the mathematical description of projectile motion?
The range (R) of the projectile is the horizontal distance it travels during the motion. Using this equation vertically, we have that a = -g (the acceleration due to gravity) and the initial velocity in the vertical direction is usina (by resolving). Hence: y = utsina – ½ gt2 (1)
How does gravity affect projectile motion?
Gravity will affect a projectile as it will decrease the height the projectile can obtain. The force of gravity acts on the object to stop its upward movement and pull it back to earth, limiting the vertical component of the projectile. As a projectile moves through the air it is slowed down by air resistance.
What is the conclusion of projectile motion?
In conclusion, projectiles travel with a parabolic trajectory due to the fact that the downward force of gravity accelerates them downward from their otherwise straight-line, gravity-free trajectory.
What is the hypothesis of projectile motion lab?
Hypothesis: The equations of motion predict that when a projectile is launched at greater heights the distance it travels forward will increase.
What are the 3 types of projectile motion?
What are the 3 types of projectile motion?
- Oblique projectile motion.
- Horizontal projectile motion.
- Projectile motion on an inclined plane.
What is the projectile formula?
h = v 0 y 2 2 g . This equation defines the maximum height of a projectile above its launch position and it depends only on the vertical component of the initial velocity.
Which factor is most important in projectile motion?
gravity
Complete answer: A projectile is an object in which the only force acting on an object is gravity. There are some examples of projectiles. When An object is dropped from its rest position it is known as a projectile which ensures that the influence of air resistance is negligible.
What two factors affect projectile?
Factors affecting the flight path of a Projectile are:
Angle of Release. Height of Release. Spin.
What are the 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 are the possible sources of error in projectile motion experiment?
The main source of error is likely to be the effect of air resistance, which is very difficult to account for theoretically at this level and is systematic in that it should decrease the range of all projectiles launched. Another source of error is likely to be the precision with which the projectile is aimed.
What are the rules of projectile motion?
Throughout the motion, the acceleration of projectile is constant and acts vertically downwards being equal to g. The angular momentum of projectile = mu cos Θ × h where the value of h denotes the height. The angle between the velocity and acceleration in the case of angular projection varies from 0 < Θ < 180 degrees.
How do you solve a projectile?
How To Solve Projectile Motion Problems In Physics – YouTube
What is projectile called?
A projectile is any object that once projected or dropped continues in motion by its own inertia and is influenced only by the downward force of gravity. By definition, a projectile has a single force that acts upon it – the force of gravity.
How many types of projectile motion are there?
The following are the three types of projectile motion: Horizontal projectile motion. Oblique projectile motion. Projectile motion on an inclined plane.
How do we use projectile motion in real life?

What are the sources of error in physics lab?
Common sources of error include instrumental, environmental, procedural, and human. All of these errors can be either random or systematic depending on how they affect the results. Instrumental error happens when the instruments being used are inaccurate, such as a balance that does not work (SF Fig. 1.4).
What are sources of random error?
Sources of random errors
natural variations in real world or experimental contexts. imprecise or unreliable measurement instruments. individual differences between participants or units. poorly controlled experimental procedures.
What are the 3 important elements of a projectile motion?
The key components that we need to remember in order to solve projectile motion problems are: Initial launch angle, θ Initial velocity, u. Time of flight, T.
What are the 4 types of projectile motion?
The only force acting on the object in projectile motion is gravity.
…
Projectile Motion: FAQs
- Oblique projectile motion.
- Horizontal projectile motion.
- Projectile motion on an inclined plane.
What angle is a projectile?
Key terms
| Term | Meaning |
|---|---|
| Launch angle | The angle of a projectile’s initial velocity when measured from the horizontal direction. These angles are typically 90 ° 90\degree 90° or less. |
Is learning projectile motion hard?
Projectile motion is often one of the most difficult topics to understand in physics classes. Most of the time, there is not a direct way to get the answer; you need to solve for a few other variables to get the answer you are looking for.
What are the 3 types of projectiles?
Three types of projectiles— the bullet, the round ball, and shot—are used in muzzleloaders.
What is a projectile give example?
A projectile is any object that is cast, fired, flung, heaved, hurled,pitched, tossed, or thrown. you throw the ball straight upward, or you kick a ball and give it a speed at an angle to the horizontal or you just drop things and make them free fall; all these are examples of projectile motion.
