Physics Examples

w = m \cdot g

$w = m \cdot g$

$w$ $w$	$=$ $=$	$?$ $?$
$m$ $m$	$=$ $=$	$10 kg$ $10 kg$
$g$ $g$	$=$ $=$	$1.635 \frac{m}{s^{2}}$ $1.635 \frac{m}{s^{2}}$

Step 1

Substitute the given values into

w = m \cdot g

$w = m \cdot g$ .

Step 1.1

Substitute

10 kg

$10 kg$ for

m

$m$ .

w = 10 kg \cdot g

$w = 10 kg \cdot g$

Step 1.2

Substitute

1.635 \frac{m}{s^{2}}

$1.635 \frac{m}{s^{2}}$ for

g

$g$ .

w = 10 kg \cdot (1.635 \frac{m}{s^{2}})

$w = 10 kg \cdot (1.635 \frac{m}{s^{2}})$

w = 10.0 kg \cdot (1.635 \frac{m}{s^{2}})

$w = 10.0 kg \cdot (1.635 \frac{m}{s^{2}})$

Step 2.1

Combine fractions.

w = 16.3500 kg \frac{m}{s^{2}}

$w = 16.3500 kg \frac{m}{s^{2}}$

Step 2.2

Combine

16.3500 kg

$16.3500 kg$ and

\frac{m}{s^{2}}

$\frac{m}{s^{2}}$ .

w = 16.3500 \frac{kg m}{s^{2}}

$w = 16.3500 \frac{kg m}{s^{2}}$

Step 2.3

Rewrite

\frac{kg m}{s^{2}}

$\frac{kg m}{s^{2}}$ as

N

$N$ .

w = 16.3500 N

$w = 16.3500 N$

w = 16.3500 N

$w = 16.3500 N$

Step 3

Round to

3

$3$ significant figures.

w = 16.4 N

$w = 16.4 N$
