momentum
friction
acceleration
True or False: Newton's First Law applies only to objects at rest.
False
Not applicable
Partially true
True
What is the SI unit of mass?
liter
gram
pound
kilogram
According to Newton's First Law, an object in motion will continue to move at a constant velocity unless acted upon by what?
inertia
external force
gravity
friction
What is the term for the property of matter that resists changes in its motion?
friction
inertia
acceleration
velocity
True or False: Inertia depends on the mass of an object.
True
Inertia depends on the color of an object
Inertia depends on the shape of an object
False
What is the formula to calculate force?
force = mass * acceleration
force = mass / acceleration
force = mass + acceleration
force = mass - acceleration
According to Newton's First Law, what happens to the motion of an object when the net force acting on it is zero?
The object remains at rest or continues to move with a constant velocity in a straight line.
The object changes direction and moves in a curved path.
The object comes to a stop and remains stationary.
The object accelerates in the opposite direction of the net force.
What is Newton's second law of motion?
The force acting on an object is equal to the velocity of the object multiplied by its mass.
The force acting on an object is equal to the distance traveled by the object divided by the time taken.
The force acting on an object is equal to the weight of the object divided by its mass.
The force acting on an object is equal to the mass of the object multiplied by its acceleration.
State the formula for Newton's second law of motion.
F = ma
F = m/a
F = ma^2
F = mv
