Force, Motion and Energy Vocabulary Term Definition acceleration The change in an objectâ€™s speed or direction (velocity) over time. f=ma The formula for finding force (N) by using mass (g) times acceleration (m/sec2). force A push or pull. Example Traveling North at 50 m/sec2 Pull Push friction The force that resists the motion of two surfaces that are touching. gravity The force of attraction between two objects. inertia An objectâ€™s tendency to resist changing its motion. motion A change in position. net force The total amount of force acting on an object. 5N, right net force 20N Newton normal force s=d/t speed velocity weight The SI unit of force. Measured with a spring scale. 15N N The force equal and opposite to gravity The formula for finding speed. Speed (m/sec) = distance (m) / time (sec) The distance traveled by an object in an amount of time. Speed with a direction. Velocity has a unit of m/sec + direction. The measure of the gravitational force of gravity on an object. Measured in Newtons or grams with a spring scale
