Question

Write all the formulas regarding to Gravitation and Motion lesson for class 9

Answer 1

Answer:

Formula regarding to Motion -

• Average speed = $\frac{Total distance travelled}{Total time taken}$
• v = $\frac{s}{t}$
• Average velocity = $\frac{initial velocity+final velocity}{2}$
• v = u + at
• s = ut + ½ at²
• 2as = v² - u²

Here, t is for time , v is for final velocity , and s is for the distance.

Formula regarding to Gravitation -

• F = G$\frac{Mm}{d²}$
• F = G$\frac{M×m}{d²}$
• F × d² = G M × m
• r³ / T² = constant
• v = 2πr / T
• Relative density = $\frac{Density of a substance}{Density of water}$

That's all i know :)
