Question

what is inertia?*
tendency of an object to resist a change in its motion.
force of attraction between two masses.

what is gravity?*
tendency of an object to resist a change in its motion.
force of attraction between two masses.

what is slope?*
the steepness of a line on a graph, equal to its vertical change divided by its horizontal change.
a place or object used for comparison to determine if an object is in motion.

Explanation:

1. Inertia is defined as an object's resistance to changes in motion.
2. Gravity is the force of attraction between masses.
3. Slope represents the steepness of a line, calculated as vertical - change over horizontal - change.

Answer:

1. Tendency of an object to resist a change in its motion.
2. Force of attraction between two masses.
3. The steepness of a line on a graph, equal to its vertical change divided by its horizontal change.
