Normal force the force of an object pushing up against you or another object, applied force, gravity, air resistance, friction, electrical, magnetic 7 how to determine the net force on an object an object at rest tends to stay at rest and an object in motion tends to stay in. How can scientists reasonable say a statement that a body at rest tends to stay at rest. An object in motion tends to stay in motion in the same direction and at the same speed, and an object at rest tends to stay at rest, unless acted upon by some net external force. Objects at rest tend to stay at rest unless acted upon by. It requires an unbalanced force to change the velocity of an object.
The focus of lesson 1 is newtons first law of motion sometimes referred to as the law of inertia. Inertia caused the quarter to continue in motion, even though the source of its motion the rolling car had stopped.
