Q

Mass vs. Weight

A

Mass = the amount of stuff that makes up an object (kg)
-Always the same no matter what your location is

Weight = force of gravity between and a planetary object (N)
-Depending your location the force will change

Q

Weight

A

Another name for force of gravity between an object and a planetary body
-measured in N

17
Q

Scales

A

They DO NOT measure weight!
-scales measure the normal force/spring forces

18
Q

Net force & acceleration are…

A

Directly proportional

19
Q

(Hooke’s Law) elasticity

A

Property that causes a material to go back to its original form

20
Q

Compression elasticity vs. Expression elasticity

A

Compression = squishy

Expression =stretchy

21
Q

Newtons 1st law

A

What causes motion to change

22
Q

Inertia

A

The tendency for an object to resist a change in motion
-The amount of mass measures an objects inertia

23
Q

Newtons 2nd law

A

The more force = more acceleration
