Force & Motion
How do we know something is in motion or if we're just seeing things?

How is Motion Described?
Motion is an object's change in position relative to a reference point. Whenever your position changes, you are in motion.
Position is the location of an object.
Reference Point is a place or objet to which another location is compared.

Getting Somewhere
Another way to describe motion is to measure it's displacement. Whenever an object changes position, it is displaced by a certain distance.
Displacement is the straight-line distance between a starting point and an end point. The displacement is the same no matter what route is traveled.

Multiple Choice
Owen walks 3 meters to his friends house and then they walk 5 meters to Sonic to get drinks. What is his displacement?

Types of Forces
Friction is a force that opposes the motion between two surfaces that are in contact.
Gravity is the universal attraction, or pull, that exists between all objects.
Magnetism is a pulling force using metals
Balanced forces are a set of forces that cancel out one another.
Unbalanced forces are a set of forces acting on an object that do not cancel one another out.
8
What is the net force?
When forces are unbalanced, the motion of an object changes. Unbalanced forces can make an object start moving, speed up, slow down, or change direction. We can calculate the unbalanced force to figure out how much it will move.
