When an object is slowing down 5 of 10 What causes acceleration? An unbalanced force 6 of 10 The larger the force... The larger the acceleration 7 of 10 Resultant force = mass x acceleration 8 of 10 What is mass usually measured in? Kg 9 of 10 What is terminal velocity? The steady speed when the upward and downward forces are balanced and you continue going down 10 of 10
