Projectile Motion
• Projectile
• Any object that moves forward due to its
inertia and accelerates downward due to
gravity.
• Projectile Motion
• The curved path of a projectile. The
vertical and horizontal components of the
motion are independent of each other.
Orbital Motion
• Orbital Motion
• The inertia component in the horizontal
direction and gravity component in the
vertical direction combine to cause the
projectile to move in a continuous curved
path.
Exercise
• Draw a sketch that shows the inertia and
gravity components with lines at right
angles causing the curved path of an
object orbiting the Earth.

Newton’s Laws of Motion
• 1. An object at rest remains at rest and an
object in motion maintains its velocity unless it
experiences an unbalanced force.
• 2. The unbalanced force acting on an object
equals the object’s mass times its acceleration.
(Force = mass x acceleration)
• 3. For every action force, there is an equal and
opposite reaction force.
• G. All objects in the universe attract each other
by the force of gravity.

1. A baseball bat snaps backwards after
hitting a ball.
2. A satellite orbits the earth.
3. A wagon is still until a child pushes it.
4. A bowling ball is harder to move than a
baseball.
5. A leaf falls to the ground.
