Acceleration (video) | Khan Academy


Acceleration is also a vector quantity, so it includes both magnitude and direction. ... a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). ... So dividing by 3 would be the same as multiplying by 1/3. ... (1/1). The units can be cancelled in the same manner (km/km, hrs/hrs).

a) 1 kg m^2 s^{-2} = ....................g cm^2 s^{-2}   

1 kilogram equivalent to one thousand grams (g) ( 1 kg = 1000 g )

One meter (m) equals one 100 centimeters (cm).

1 m = 100 cm

1 m^2 = 10^4 cm^2

1 kg m^2 s^{-2} = 1000 g * 10^4 cm^2 * s^{-2}

1kg m^2 s^{-2} = 10^{7} gcm^2s^{-2}


b) 1 m = ............ ly   (light year)

Speed of light c = 3* 10^{8} m/s

Time = 1 year = 365 * 24 * 60 * 60 =  31536000 [/math] seconds

\text{ speed } = \frac{\text{ Distance }}{\text{ time }}

\text{ Distance }=speed*time

\text{ Distance } = 3* 10^{8} * 31536000

\text{ Distance } = 9.5 * 10^{15} m

9.5 * 10^{15} m  =  1 light year

1 m = ?

1 m = \frac{1}{9.5 * 10^{15}} \text{ light years} = 1.1 * 10^{-16} \text{ light years}


c)   3.0 ms^{-2} = ...............kmh^{-2}

Converting seconds to hours

1 sec = \frac{1}{60 * 60} hours

[math] 1 sec^2 = [\frac{1}{60 * 60}]^2 \text{ hours }^2[/math]

Converting meters to kilometers

1 m = \frac{1}{1000} km


[math] 3.0 ms^{-2} = 3.0 * \frac{1}{1000} km * [\frac{1}{60 * 60}]^{-2} h^{-2} [/math]

3.0 ms^{-2} = 3 * 10^{-3} * (3600)^2 kg h^{-2}

3.0 ms^{-2} = 3.9 * 10^{4} kg h^{-2}


d)

G = 6.67 * 10^{-11} Nm^2 kg^{-2} = ................ cm^3 s^{-2} g^{-1}

1 \text{ newton } = 1 kg m s^{-2}

[math] G = 6.67 * 10^{-11} Nm^2 kg^{-2} = 6.67 * 10^{-11} [1 kg m s^{-2}] m^2 kg^{-2}[/math]  

G = 6.67 * 10^{-11} kg^{-1} m^3 s^{-2}

G = 6.67 * 10^{-11} (10^3)^{-1} g^{-1} (10^{2})^3 cm^{3} s^{-2}

G = 6.67 * 10^{-8} g^{-1}(cm)^{3} s^{-2}
