Mass cancels the property of inertia.
The table shows the details of three moving objects.
A student claims that it is easier to stop Object 2 than to stop Objects 1 and 3. What justifies the student’s claim?
Object 2 has the least mass, so it has the least inertia.
Object 2 has the least speed, so it requires the most force to stop.
Object 2 is the slowest, so it experiences the least friction.
Object 2 is the lightest, so it experiences the smallest gravitational force.
