arbitrarily chosen reference frame and arbitrarily chosen units of size. In order to share information with other people, these choices must also be shared. Why do objects fall to the ground? MS-PS2-2 Why do some objects move further than others? MS-PS2-2 What direction will objects move when a force is applied? MS-PS2-2 How is the motion of an object related to the point of reference? MS-PS2-2 How are distance and speed measured? MS-PS2-2 How is an object’s motion described in terms of speed and motion? a bowling ball using only a rubber mallet. Tapping the ball with the mallet can only move the ball, and the mallet cannot be kept in constant contact with the ball. This forces the students to observe the direction of the taps necessary to start the ball moving, keep the ball moving in a given direction, and to stop the ball and bring it to rest. The students identify the mallet as a contact force. Students will define the terms balanced and unbalanced forces in their own words; they will also provide examples of each force. Students will participate in a kinesthetic lesson on balanced and unbalanced forces by playing tug-of-war with their classmates. Relate balanced forces to when the pull is equal from each team energy Pull Push Relative position Speed Unbalanced force Velocity Zero net force and friction are appropriate.
