1. What causes the path of a projectile to be curved?
Gravity
What causes the path of a projectile to be curved?

2. Gravity Any two masses that exert an attractive force on each other
Depends on mass and distance between objects
How so?

3. Weight
Gravitational force exerted on an object measured in units called Newtons
The greater an object’s mass, the stronger the gravitational force on it
What is the difference between mass and weight?

4. Projectile Motion
Projectile-anything that is thrown or shot through air
A projectile follows a curved path and has:
Horizontal Motion and Vertical Motion
(Motion Parallel to Earth’s Surface) (Motion Perpendicular to Earth’s Surface)

5. Momentum
The amount of motion of a moving object measured by the product of mass times velocity
p=mv (p=momentum)

6. Centripetal Force
Force acting toward the center of a curved or circular path
