State Newton’s First Law of Motion

An object at rest will remain at rest and an object moving at a constant velocity will continue moving at a constant velocity, unless it is acted upon by an unbalanced force. Inertia depends on mass page 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.
