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 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

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
