100

Solving for Acceleration

a = force/mass

100

A push or a pull

Force

100

Which law of motion? "You will lean forward when the car stops."

First law of motion

100

Is the net force larger if two forces are pushing against each other? Would you add or subtract?

No, they subtract from each other

100

Force that acts to oppose sliding between surfaces that are touching

Friction

200

Solving for Force

N = mass x acceleration

200

Point in an object that moves as if all of the object's mass were concentrated at that point

Center of mass

200

Which law of motion? "The swimmer pushed down on the diving board and then was propelled into the air."

Third law of motion

200

A measurement of force that depends on gravity, measured in newtons

Weight

200

Would a ball roll faster on carpet than on woodflooring? Why?

No, friction would slow it down

300

Solving for Mass

m = force / acceleration

300

Two or more forces whose effects cancel each other out and do not change the motion of an object

Balanced forces

300

Which law of motion? "It takes more force to roll a bowling ball than a tennis ball."

Second law of motion

300

Is the net force larger if two forces are pushing with each other in the same direction? Would you add or subtract?

Yes, the combine for a greater force

300

What would allow you to sled down a snowy hill faster?


Smoother snow, fewer obstacles, sleeker sled

400

Name the three units for the acceleration formula

m/s2, N, kg

400

Combination of all forces acting on a subject

Net Force

400

Which law of motion? "A bird's wings push down on the air, and the air pushes up on the wings, creating flight."

Third law of motion

400

In an unbalanced force, where does the motion head?

In the direction of the stronger force

400

What are the two main forces that causes an object in motion to stop?

Force and gravity

500

If your car has a mass of 2,000 kg and it is accelerating at 27 m/s2, how strong is the force? 

54,000 N

500

Two or more forces acting on an object that do not cancel, and cause the object to accelerate

Unbalanced forces

500

Which law of motion? "If you slam a ketchup bottle on the counter, the ketchup moves down to the bottom of the bottle."

First law of motion

500

If you throw a basketball at the hoop harder, will it have more of a curved path or less?

Less, because the acceleration is stronger than the gravity for longer

500

What are the three types of friction?

Static, rolling, sliding
