Chapter 2 Forces Flashcards
Newton is?
A unit of measure that equals the force required to accelerate 1 kilogram of mass at 1 meter per second per second.
Force is?
A push or pull exerted on an object.
Net force is?
The overall force on an object when all the individual forces acting on it are added together.
Friction is?
- The force that two surfaces exert on each other when they rub against each other. 2. The transfer of electrons from one uncharged object to another uncharged object by rubbing.
Sliding friction is?
Friction that occurs when one solid surface slides over another.
Static friction is?
Friction that acts between objects that are not moving.
Fluid friction is?
Friction that occurs as an object moves through a fluid.
Rolling friction is?
Friction that occurs when an object rolls over a surface.
Gravity is?
The attractive force between objects; the force that moves objects downhill.
Mass is?
The amount of matter in an object.
Weight is?
A measure of the force of gravity acting on an object.
Inertia is?
The tendency of an object to resist a change in motion.
Momentum is?
The product of an object’s mass and velocity.
Law of conservation of momentum is?
The rule that in the absence of outside forces the total momentum of objects that interact does not change.
Free fall is?
The motion of a falling object when the only force acting on it is gravity.
