In what ways do forces affect an object`s motion?
... • Inertia is the tendency of an object to resist a change of motion Newton’s first law of motion states that an object will remain at rest or in constant straight-line motion unless unbalanced forces act on the object. • Newton’s second law of motion states that the acceleration of an object incre ...
