1. Newton's First Law of Motion is also known as the Law of:
Acceleration
Inertia
Action-Reaction
Conservation of Energy
2. Which of the following statements best describes an object at rest according to Newton's First Law?
It will spontaneously start moving.
It will remain at rest unless acted upon by an unbalanced force.
It will eventually gain speed due to gravity.
Its velocity will constantly change.
1. An object in motion will eventually come to a stop even if no external forces act on it.
True
False
2. Inertia is directly proportional to an object's mass.
True
False
1. Newton's First Law states that an object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an force.
2. The property of an object to resist changes in its state of motion is called .
1. Explain the concept of inertia using a real-world example.
2. A hockey puck slides across a frictionless ice surface. Describe its motion according to Newton's First Law if no external forces are applied.
Match each term on the left with its definition on the right.
1. Inertia
a. The tendency of an object to resist changes in its state of motion.
2. Unbalanced Force
b. A force that results in a net force greater than zero, causing a change in motion.
3. Equilibrium
c. A state where all forces acting on an object are balanced, resulting in no change in motion.
