Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change an object's motion; unbalanced forces do.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.
