Newton's Laws Gratto
| Question | Answer |
|---|---|
| What is the combination of all the forces acting on an object called? | net force |
| What is it called when the forces acting on an object that combine and form a net force of zero? | balanced force |
| What is it called when the forces acting on an object that combine and form a net force that is not zero? | unbalanced force |
| If the net force on an object is zero, the motion of the object does not change is called what? | Newton's first law of motion |
| What is the tendency of an object to resist a change in its motion called? | inertia |
| What is the acceleration of an object is equal to the net force acting on the object divided by the object's mass called? | Newton's second law of motion |
| Any motion in which an object is moving along a curved path is called what? | circular motion |
| In circular motion, a force that acts perpendicular to the direction of motion, toward the center of the curve is called what? | centripetal force |
| When one object exerts a force on a second object, the second object exerts an equal force in the opposite direction on the first object is called what? | Newton's third law of motion |
| What is the forces two objects apply to each other called? | force pair |
| What is a measure of how hard it is to stop a moving object called? | momentum |
| What is the total momentum of a group of objects stays the same unless outside forces act on the objects called? | Law of conservation of momentum |
