Which of the following is Newton's 1st law?
For every action, there is an equal and opposite reaction.
The acceleration of an object is produced by a net force and is inversely proportional to the mass of the object.
An object will remain at rest or in motion unless an outside force acts upon it.
A force is a push or pulll
Which of the following is Newton's 2nd law?
For every action, there is an equal and opposite reaction.
The acceleration of an object is produced by a net force and is inversely proportional to the mass of the object.
An object will remain at rest or in motion unless an outside force acts upon it.
A force is a push or pulll

What is the acceleration of a car moving at a constant velocity of 30 m/s?
0 m/s2
30 m/s2
90 m/s2
120 m/s2
If a car goes from 30 m/s to 50 m/s in 2 seconds, what is its acceleration?
40 m/s2
20 m/s2
2 m/s2

What is the difference between weight and mass?
In order for an object to be in equilibrium:
All forces must be equal and opposite
One force over powers the others and causes an object to accelerate
All forces face the same direction
All forces on the object converge
