1. Projectile Motion

2. Horizontal and Vertical Motion
Position, velocity and acceleration are vectors.
These vectors can be separated into components.
Choose x for horizontal
Choose y for vertical
The equations for constant acceleration can be written separately in each coordinate.

3. Vector Gravity The gravitational acceleration is a vector.
The magnitude is 9.8 m/s2.
The direction is down.
If there is only constant gravitational acceleration in the -y direction, the equations simplify for x.

5. Vertical Pull
All falling objects are subject to the same gravitational acceleration.
The horizontal component doesn’t affect the downward acceleration.

6. Moving Target The initial horizontal velocity doesn’t matter.
All objects fall at the same vertical rate (neglecting friction).
At the collision the target fell a distance y = -d.
The time it fell comes from the acceleration.

7. Horizontal Speed
The point of collision measures the distance dropped since the ball was fired.
The time determines the horizontal velocity of the ball.
The angle of the launcher gives the total velocity.
