12.1 Flashcards
The force that causes a 1-kilogram mass to accelerate at a rate of 1 meter per second
Newton
A push or pull that acts On an object
Force
The over all force acting on an object after all the forces are combined
Net force
A force that opposes the motion of objects that touch as they move past each other
Friction
The friction force that acts on objects that are not moving
Static friction
A force that opposes the direction of motion of an object as it slides over the surface
Sliding friction
The friction force that acts on rolling objects
Rolling objects
Opposes the motion of an object through a liquid
Fluid friction
Fluid friction acting on an object moving through the air
Air resistance
Force that acts between any two masses
Gravity
The constant velocity of a falling object when the force of air resistance equals the force of gravity
Terminal velocity
The motion of a falling object after it is given an initial forward velocity
Projectile motion
