Inertia depends on mass page 349350 textbook The ability to do work is called a.Conversion b. friction c. Velocity d.energy D. energy The energy associated with motion is called a. Nuclear energy b.Elastic potential energy c. Kinetic energy d.Gravitational potential energy C. Kinetic energy An example of something that stores chemical energy is a. a match b. microwave c. Lightning d. light A Match State Newton’s Second Law of Motion Acceleration depends on the object’s mass and on the net force acting on the object. Net force = Acceleration X Mass What type of conversion is taking place when natural gas is used to heat water? a. Mechanical energy into electromagnetic energy b. Thermal energy into mechanical energy c. Electromagnetic energy into chemical energy d. Chemical energy into thermal energy D. Chemical energy into thermal energy When you rub your hands together on a cold day, you use friction to convert a. Nuclear energy into electrical b. Thermal energy into nuclear c. Electrical energy into electromagnetic d. Mechanical energy into thermal energy D. Mechanical energy into thermal energy A helicopter uses his main propeller a. To keep the helicopter from spinning b.To move the helicopter forward c. To create a force to lift it off the ground d.To move the helicopter backwards C. To create a force to lift it off the ground State Newton’s third Law of Motion If one object exerts a force on another object, then the second object exerts a force of equal strength in the opposite direction on the first object. Another way to say it is for every action there is an equal but opposite reaction. The process of burning a fuel is called a. Conduction b.Acceleration c. Meltdown d.Combustion D. Combustion When fossil fuels are burned, their chemical potential energy is converted into a. Thermal energy b.Mechanical energy c. Nuclear energy d.Electrical energy A. Thermal energy The type of energy stored by fossil fuels such as coal is a. Kinetic b. Mechanical energy c. Electromagnetic energy d.Chemical potential energy D.
