Question

inertia is a property of mass in which an object at rest wants to stay at rest,and an object that is moving wants to _____ a. also stay at rest b. stay moving along a straight line unless acted upon by another force c. stay moving in in a circular motion unless acted upon by another force d. stay moving in a straight line,but only if it has been acted upon by another force

Answer 1

Inertia is a property of mass in which an object at rest wants to stay at rest, and an object that is moving wants to b. stay moving along a straight line unless acted upon by another force.

Explanation:

Newton's first law states:

• "Any object at rest tends to remain at rest and any object in motion tends to stay in motion unless an external push or pull is applied on it"
• First law of motion introduces the concept of Inertia.
• Inertia is the property of matter or mass which resists any change in state of system.
• Inertia depends on the mass of body. Greater the mass of body, it has more inertial property or it resists force more strongly than objects with lower mass.
• Object that is already moving will stay in motion in a straight line because changing direction of motion will cause it to change velocity and produce acceleration.
• So, uniform motion and rest is maintained by the body as a result of inertia.
