Unit 6 Notes. Free-Fall: When an object is flying through the air and the only force acting on it is gravity. In our mini-lab with the cannons, we analyzed.

Aim: How can we solve problems dealing with horizontally fired objects? Do Now: An object falls freely for 75 m. How long does it take to reach the ground?

Why is it so hard to get rubbish in the bin?

Projectiles (2D) A projectile is any object that is in a state of freefall, or in other words an object that is only acted upon by the force of gravity.

Projectiles have two types of motion at the same time: Horizontal Vector An object travels at a constant speed (assuming no air resistance and no other.

Horizontally shot projectiles

2 If you drop a ball straight down and throw a ball sideways at the same time from the same height, which one will hit first or will they hit at the same time?

Projectiles A projectile is: Examples:

Vx = Viy= Viy= __________ m/s

Vx The horizontal speed is ________________ because we:

Viy a becomes a y since a y = __________

Equations Vx = Δy =
