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.
Newton’s Laws of Motion
• 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.
