|---|---|---|---|---|---|
| Force | A push or pull on an object.
🗑
|
||||
| Contact Force | Is a push or a pull on one object by another that is touching it.
🗑
|
||||
| Noncontact Force | A force that one object can apply to another object without touching it.
🗑
|
||||
| Gravity | Is an attractive force that exist between all the objects that have mass.
🗑
|
||||
| Mass | Is the amount of matter in an object.
🗑
|
||||
| Weight | Is gravitational force exerted on an object.
🗑
|
||||
| Friction | Is a force that resist the motion of two surface that are touching.
🗑
|
||||
| Net Force | The combination of all the force acting on an object.
🗑
|
||||
| Balanced Force | Forces acting on an object that combine and form a net force of zero.
🗑
|
||||
| Unbalanced Force | Force acting on an object that combine and form a net force that is not zero.
🗑
|
||||
| Newtons's First Law of Motion | If the net force on an object is zero.
🗑
|
||||
| Inertia | The tendency of an object to resist a change in its motion.
🗑
|
||||
| Newton's Second Law of Motion | The acceleration of an object is equal to the net force acting on an object divided by the object's mass.
🗑
|
||||
| Circular Motion | Is any motion in which an object is moving along a curved path
🗑
|
||||
| Centripetal Force | In circular motion, a force that acts perpendicular to the direction of motion, toward the center of the curve.
🗑
|
||||
| Newton's Third Law of Motion | When one object exerts a force on a second object, the second exerts equal force in the opposite direction on the first object.
🗑
|
||||
| Momentum | Is the measure of how hard it is to stop a moving object.
🗑
|
||||
| Law of Conservation of Momentum | The total momentum of a group of objects stays the same unless outside forces act on an object.
🗑
