Which. describe newtons law of univesel gravitation
Fed [463]

Newton's law of universal gravitation, says that every particle attracts every other particle in the universe with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

Or in simple words, every particle in the world attracts each other to themselves, but the particle with most mass would attract with more force compared to a particle with less mass.

A ball with a mass of 5.0 g is moving at a speed of 2.0 m/s. Would doubling the mass or doubling the speed have a greater effect
Arte-miy333 [17]

Answer:

Yes

Explanation:

Kinetic energy is K.E1/2mv2 so that means it is directly proportional to mass and velocity.

Big Bob is on his Harley and moving at 14.0m/s. He then accelerates to a velocity of 25m/s over a distance of 0.250 km. What is
Xelga [282]

As we know that it has all given data given as

v_i = 14 m/s

v_f = 25 m/s

distance moved = 0.250 km = 250 m

now we can use kinematics to find acceleration

v_f^2 - v_i^2 = 2 a d

25^2 - 14^2 = 2 * a * 250

a = 0.86 m/s^2

so it will accelerate at rate of 0.86 m/s^2
