What is the vertical acceleration of a projectile?
0 m/s2
-9.8 m/s2
What force acts in the y direction (vertical) that causes an object to travel in a parabolic (curved) path?
Friction
Gravity
Tension
No force acting.
Who do you agree with?
Anita: “A projectile’s vx changes because of gravity, and its vy remains constant.”
Barry: “Both vx and vy are constant.”
Chris: “A projectile has no acceleration in the vertical dimension but it does accelerate horizontally.”
Dave: “A projectile has vertical acceleration and a constant horizontal velocity”
