List of all 2d motion and projectile equations?

In summary, there are two types of motion in projectile motion: with acceleration and without acceleration. For motion with acceleration, the equations are the same as 1-D equations for constant acceleration, with the velocity being either vy or v·sinθ. For motion without acceleration, the equation is \Delta x \ = \ v_x \ \Delta t, with an alternative form using v·cosθ for the velocity component.

Welcome to Physics Forums.

For the direction with acceleration (vertical, in the case of projectile motion), the equations are the same as the 1-D equations for constant acceleration. Just be aware that the velocity can be expressed as either vy or v·sinθ.

For the direction without acceleration, it is motion with a constant velocity and there is really just one equation, [itex]\Delta x \ = \ v_x \ \Delta t[/itex]. An alternative form of the same equation is to express the velocity component as v·cosθ.

Hope that helps.
 

1. What is 2D motion and projectile?

2D motion and projectile refers to the movement of an object in two dimensions (horizontal and vertical) and the path that a projectile follows under the influence of gravity.

2. What are the basic equations for 2D motion?

The basic equations for 2D motion include the equations for displacement, velocity, and acceleration in both the horizontal and vertical directions. These equations are:
- Horizontal displacement: x = x0 + v0xt + 1/2at2
- Vertical displacement: y = y0 + v0yt + 1/2gt2
- Horizontal velocity: vx = v0x + at
- Vertical velocity: vy = v0y + gt
- Horizontal acceleration: ax = 0 (assuming no air resistance)
- Vertical acceleration: ay = -g (due to gravity)

3. What is the equation for projectile motion?

The equation for projectile motion is y = y0 + v0yt + 1/2gt2, where y is the vertical displacement, y0 is the initial height, v0y is the initial vertical velocity, g is the acceleration due to gravity, and t is time.

4. How do you find the maximum height of a projectile?

To find the maximum height of a projectile, you can use the equation y = y0 + v0yt + 1/2gt2 and set the vertical velocity to zero (since the projectile reaches its maximum height when it stops moving vertically). This will give you the maximum height as y = y0 + v0y2/2g.

5. How can you calculate the range of a projectile?

To calculate the range of a projectile, you can use the equation x = x0 + v0xt + 1/2at2 and set the vertical displacement to zero (since the projectile starts and ends at the same height). This will give you the range as x = v0xt.
