Question 1.
Define inertia.
Show hintHide hint
Think about how objects behave when forces are applied.
Question 2.
What unit is used to measure mass?
Show hintHide hint
Mass is a measure of matter.
3Question 3.
What does inertia describe?
- A) The tendency of an object to remain at rest
- B) The change in an object's position
- C) The velocity of an object
- D) The acceleration of an object
Show hintHide hint
Think about how objects behave when no forces act on them.
4Question 4.
True or False: All objects with the same mass have the same inertia.
- True
- False
Show hintHide hint
Recall the definition of inertia.
Question 5.
Consider a heavy box with a mass of 25 kg. How much force is needed to accelerate it at 2 m/s²?
Show hintHide hint
Apply Newton's second law of motion.
Question 6.
A marble rolls down an inclined plane, where friction can be ignored. If it starts with no force acting and rolls down gaining speed, describe the forces acting on it and what is its inertia.
Show hintHide hint
Consider how inertia resists changes to motion.
