Today’s science starter Day 3: Forces and Motion
Contact vs. Noncontact forces Push or pull on an object that is touching it Push or pull on an object without touching it Ex: gravity, friction
Calculating net force
Net force Calculated by adding same direction forces and subtracting opposing forces
