Applying Laws of Projectile Motion to 45 Degree Angle

In summary, the conversation discusses projectile motion and its applicable laws, specifically Newton's 2nd law and gravity. The conversation also touches on the importance of defining the problem when solving for projectile motion, with an example of determining the farthest distance with different angles. The final objective is to find the angle that will maximize the horizontal distance of a projectile.

in a projectile motion, what law could be applicable to this sitaution?
if u want an example, umm let's say..
ur measuring porjectile motion for 45 degrees.,,
hat law or theory could be applicable to this?

The usual suspects: Newton's 2nd law and gravity.

All projectile motion is essentially the same: The vertical motion is accelerated downward; the horizontal motion is constant speed.

isnt it that to solve somehting like this needs a problem (according to the scientific method) and to make the problem, we have to base it on the objectives?
then what would be the objectives on this problem?
>to measure how far the 45 degree angle would be?
thanks

The laws regarding projectile motion are well known. Of course, to solve any problem you first need to know what the problem is. Do you have a specific problem in mind?
 
  • #5
As Doc Al asked you need a specific problem. If your talking about projectile motion a few things come to mind. The angle(can be 45 degrees), acceleration, velocity, position...

umm.. i was planning to measure the projectile motion ith differnet angles..
so my problem would be um..
which angle will launch the farthest distance
is that enough?

What angle will maximize a projectiles horizontal distance? I think that would be a bit more exact.

thank you so much all!
 

1. How do you calculate the horizontal and vertical components of a projectile at a 45 degree angle?

To calculate the horizontal and vertical components of a projectile at a 45 degree angle, you can use the following formulas:
Horizontal component = initial velocity * cos(45)
Vertical component = initial velocity * sin(45)

2. What is the equation for the range of a projectile at a 45 degree angle?

The equation for the range of a projectile at a 45 degree angle is:
Range = (initial velocity)^2 * sin(90) / gravitational acceleration

3. How does the angle of projection affect the range of a projectile?

The angle of projection affects the range of a projectile in the following ways:
- A lower angle (less than 45 degrees) will result in a shorter range.
- A higher angle (greater than 45 degrees) will result in a longer range.
- At a 45 degree angle, the range will be maximum.

4. Can the laws of projectile motion be applied to objects thrown at an angle other than 45 degrees?

Yes, the laws of projectile motion can be applied to objects thrown at any angle. The equations for calculating the horizontal and vertical components, as well as the range, will vary depending on the angle of projection.

5. How does air resistance affect the motion of a projectile at a 45 degree angle?

Air resistance can affect the motion of a projectile at a 45 degree angle by reducing its velocity and therefore decreasing its range. The extent to which air resistance affects the projectile will depend on the density of the air and the shape and size of the projectile.
