Forces in Motion 2017
Terms in this set (25)
Change of position
A push or a pull; measured in Newtons.
Force across a distance. The wall was pushed with a force of 100 N and it moved 2 cm. 200 Joules of work was done on the wall.
Units for work.
the rate at which velocity changes
(F.V. - O.V. / T)
The combination of all forces acting on an object. Ava applied 20 Newton of force and Summer applied 20 Newtons of force (both in the same direction) to a table. Their net force would be 40 Newtons. Subtract when forces are in opposing directions.
the force opposing the motion of surfaces
Fluid, sliding, rolling and static are all types of friction.
Invisible force of attraction due to mass and distance.
Speed in a given direction
The distance an object travels per unit time. Speed is a rate. S=D/T
equal forces acting on one object in opposite directions. Object will not be moving. Similar to static friction.
Newton's 1st. Law (54, 55)
The "Inertia" law. Objects at rest/motion will stay at rest/motion until an outside, unbalanced force acts upon it.
The resistance to motion. The higher the mass, the higher the inertia. Seat belts are inertia belts. R.M.
Newton's Second Law
Force = Mass x Acceleration.
Changing one will affect the rest. If you increase the mass, the acceleration will decrease. If you increase the force, the acceleration will increase.
Newton's Third Law
for every action there is an equal and opposite reaction
Mass x Velocity
A representation of something too big, small, extinct, dangerous, etc. to have in a lab.
What variables affected your plane's launch?
Share any interesting facts about Newton's childhood.
Mass X Acceleration
What are any of Newton's great accomplishments?
Two or more elements chemically combined
How tightly-packed something is. D=M/V.
1.0 g/ml is the density of water.
