Understanding Projectile Motion: Definitions and Concepts

In summary, the conversation discusses projectile motion and the concepts of time of flight and range. It is clarified that these values are not solely dependent on the point of projection, but also on the speed and angle of the projectile. Other variables such as the angle of firing and the speed at launch also influence these values.

Hello!

I'm in the 11th grade, and my class has started projectile motion. It's basic for the most part, but a few terms confused me at times. For instance, when a question asks for time of flight, is it solely dependent on where that objected is projected from (e.g., from a height, or from the ground)? Also, when a questions asks for range, in the same regard, is it solely dependent on the height/ground released? '

Thanks!
Neither of those is solely "dependent on where that object is projected from"! They are also dependent on the speed and angle at which the projective is fired. (That would seem to me obvious. Is that really the question you intended to ask?)

Hello Rohan, welcome to PF :smile: !

No, there are a few more variables that influence that time and range. Both you can well imagine, in fact:
the angle of firing
the speed at launch

Does that sound reasonable?
 

Related to Understanding Projectile Motion: Definitions and Concepts

1. What is projectile motion?

Projectile motion is the motion of an object that is launched into the air and then moves under the influence of gravity alone.

2. What is the difference between a projectile and a non-projectile motion?

A projectile motion is a type of motion where an object is only influenced by gravity, while a non-projectile motion is a type of motion where an object is influenced by multiple forces such as friction and air resistance.

3. What are the key components of projectile motion?

The key components of projectile motion are initial velocity, angle of launch, and gravitational acceleration.

4. How does the angle of launch affect projectile motion?

The angle of launch affects the horizontal and vertical components of the object's velocity. The greater the angle, the higher the object will go and the longer it will take to reach the ground.

5. What is the formula for calculating the maximum height of a projectile?

The formula for calculating the maximum height of a projectile is h = (v2sin2θ)/2g, where h is the maximum height, v is the initial velocity, θ is the angle of launch, and g is the gravitational acceleration.
