Chapter 12: Matter in Motion Reference Point • An object that appears to stay in place that helps detect motion Speed • Total distance / total time – mph – m/s Velocity • Speed plus direction Acceleration • Rate of which velocity changes – m/s² – Positive or negative Measuring Acceleration Force • a Push or Pull • Measured in –Newtons • Net Force = – Combined of forces acting on an object Unbalanced Forces • When the net force is greater than 0 Newton • Unbalanced force can: – Start motion – Change motion – Stop motion Friction • Force that opposes motion • Depends on the materials Kinetic Friction • “Moving” • Sliding Kinetic Friction • Rolling Kinetic Friction Friction • Helpful – Brakes – Pencil marks – Match Friction • Harmful Terms to Know • Friction • Net force • Force • Kinetic friction • Motion • Velocity • Acceleration
