2. Motion “In physics, motion is a change in position of an object with respect to time.” Running the bases Moving the bat Pitching Catching

3. Speed “In kinematics, the speed of an object is the magnitude of its velocity.” Running the bases The speed of the bat Speed of throwing a ball Running to make a catch

4. Velocity “In physics, velocity is the measurement of the rate and direction of change in the position of an object.” Speed of a hit Speed of a swing When throwing different types of balls Swinging Rotation of ball

5. Sliding Friction “Friction is the force resisting the relative motion of solid surfaces, fluid layers, and/or material elements sliding against each other.” When sliding into a base Sliding to catch a ball When a ball is rolling

6. Gravity “Gravity, is a natural phenomenon by which physical bodies attract with a force proportional to their mass.” When a ball falls down from a hit When throwing a ball and it drops
