# percent error (theoretical/actual value)?

sort of lost here... I know it's theoretical value - actual / theoretical x 100% but still lost. Any help appreciated

Acceleration measured (m/s2): .025

Acceleration calculated (m/s2): 10

total mass was .400 (kg)

Update:

figures... i'm completely lost here

heres what my table looks like

mass of wagen: .399

mass of hanging line: .001

acceleration measured .025

Applied Fnet (kg): ?

Total Mass: .400

Acceleration calculated: 10

% error: ?

the measured value is so far off that you probably made a mistake somewhere.

The percent error would be huge.

(10 - 0.025)/10 = 99.75% error by your formula

but actually your measurement is off by 3 orders of magnitude. Like measuring a 60 mph auto at 60000 mph.

.

• First, you're taking the version of your value and the easily value, 396.3-330 = sixty six.3 then you fairly take that difference and divide it by using the easily value : sixty six.3/330 = .20 so the % blunders is 20% wish this helps :D
