Newton's First Law of motion

Laws of Motion

• Inertia is a property of matter
• Inertia is the likelihood of an object to resist a change in motion
• The more mass an object has the more inertia it has
• An unbalanced force is the only thing that can overcome inertia

AN object in motion stays in motion

• If you throw a football it will stay in motion until gravity pulls it down or someone catches it.
• If a running back is tackled the unbalanced force is the defense
• When the kick returner is returning a kick he is in motion
• When he is tackled he is at rest

An object at rest stays at rest

• When the center has the ball the ball is at rest and when the center snaps the ball it is in motion
• When the placeholder is holding the football the football is at rest until the kicker kicks it.
• The kicker is the unbalanced force
