Newton's Laws of Motion - First Law (Inertia): What does the first law of motion state?
An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.
For every action, there is an equal and opposite reaction.
The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
Energy cannot be created or destroyed, only transformed.
Newton's Laws of Motion - First Law (Inertia): How does this law apply to a CO2 dragster?
A CO2 dragster remains at rest until acted upon by an external force.
A CO2 dragster accelerates indefinitely without any force.
A CO2 dragster changes direction without any force.
A CO2 dragster stops immediately when the force is removed.
Newton's Laws of Motion - Second Law (F=ma): What is the formula for the second law of motion?
F = ma
F = m/a
F = a/m
F = m + a
Explain how the mass of the dragster affects its acceleration.
The greater the mass, the greater the acceleration.
The greater the mass, the lesser the acceleration.
The mass does not affect the acceleration.
The mass affects only the speed, not the acceleration.
Newton's Laws of Motion - Third Law (Action and Reaction): Which of the following best describes the third law of motion?
For every action, there is an equal and opposite reaction.
An object at rest stays at rest unless acted upon by an external force.
The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
Energy cannot be created or destroyed, only transformed.
