use the newtons 1st law of motion notes in google classroom
newtons 1st law of motion: newtons 1st law of motion, also known as the law of inertia,
states that if an object is at rest or moving with a constant velocity in a straight line, it will remain
at rest or keep moving in that same way unless acted upon by an external force. inertia is the
tendency of an object to resist changes in its motion. the greater the mass of an object, the
greater its inertia. net force is the total force acting on an object, found by adding up all the
forces. if the net force is zero, the object is in equilibrium, meaning it is either at rest or moving
at a constant velocity.

multiple choice questions: choose the correct answer from the choices for each question.

1. which of the following best describes inertia?

a) the force that changes an objects motion
b) the tendency of an object to resist changes in its motion
c) the speed at which an object moves
d) the acceleration of an object

1. according to newtons 1st law, what will happen to an object at rest if no exter

acts on it?
a) it will start to move
b) it will accelerate
c) it will remain at rest
d) it will spin

1. what does it mean when an object is in equilibrium?

a) the net force is not zero
b) the object is changing direction
c) the object is at rest or moving at constant velocity
d) the object is speeding up

Explanation:

1. As per the text, Newton's 1st Law is also called the Law of Inertia.
2. The text clearly defines inertia as the tendency of an object to resist changes in motion.
3. The note states that an object remains at rest or in motion at constant velocity unless acted upon by an external force.
4. The note defines net force as the total force acting on an object.
5. When net force is zero, the object is in equilibrium (either at rest or moving at constant velocity).

For multiple - choice:

1. Inertia is defined as the tendency of an object to resist changes in its motion (from the text).
2. Newton's 1st Law states an object at rest remains at rest if no external force acts (from the text).
3. The note says when net force is zero (object in equilibrium), it is either at rest or moving at constant velocity.

Multiple Choice:
