Newton's Laws & Friction

a = \frac{F_{net}}{m} = \frac{0}{10} = 0\,\text{m/s}^2

Normal force (N = mg)98.1 N

Limiting friction (μN)29.4 N

Friction force now20.0 N

Net force0.0 N

Acceleration0.00 m/s²

StateStationary

Applied force20 N

Mass10 kg

Push hard enough to make the block start moving
Push the block (applied force above 0) but keep it stationary — friction is holding it there
Get the acceleration to exactly 2 m/s²
Switch to ice and get the block moving with less than 10 N of applied force
Switch to rubber and still get the block moving
