What are the three laws of motion and examples​

Physics
1 answer:
madreJ [45]4 years ago
8 0

Explanation:

<u>In</u><u> </u><u>Newton's</u><u> </u><u>1</u><u> </u><u>law</u>, an object will not change its motion unless a force acts on it.

The motion of a ball falling down through the atmosphere, or a model rocket being launched up into the atmosphere are both examples of Newton's first law. 

<u>In</u><u> </u><u>Newton's</u><u> </u><u>2</u><u> </u><u>law</u>, the force on an object is equal to its mass times its acceleration.

Riding your bicycle is a good example of this law of motion at work. ... Your leg muscles pushing pushing on the pedals of your bicycle is the force. When you push on the pedals, your bicycle accelerates.

<u>In</u><u> </u><u>Newton's</u><u> </u><u>3</u><u> </u><u>law</u>, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.

For example, when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air.

The branch of science concerning heat flow and energy conversions is called thermodynamics. The pattern that takes place in the ecosystem regarding the flow of energy is from a higher energy state t a lower energy state. It follows the second law of thermodynamics, the entropy in which all things go into the chaotic state from a higher form into lower form.

john throws .4 kg ball with velocity of 18 m/s. Hits .2 kg bottle and bottle flies 25 m/s. How fast is ball traveling after hitt
UNO [17]

Answer:

5.5 m/s

Explanation:

Assuming the bottle is initially stationary, we can write the law of conservation of momentum as follows:

p_i = p_f\\m_b u_b = m_b v_b + m_B v_B

where

m_b = 0.4 kg is the mass of the ball

u_b = 18 m/s is the initial velocity of the ball

m_B = 0.2 kg is the mass of the bottle

v_B = 25 m/s is the final velocity of the bottle

v_b is the final velocity of the ball

Solving for v_b,

v_b = \frac{m_b u_b - m_B v_B}{m_b}=\frac{(0.4 kg)(18 m/s)-(0.2 kg)(25 m/s)}{0.4 kg}=5.5 m/s

timama [110]

Answer:

Explanation:

The intensity of polarised light after polarization through angle θ

I = I₀ cos²θ

Here θ = 23 for first polariser

Intensity after first polarisation

= I₀ cos²23 = .846 I₀

For second polariser θ = 90 - 23 = 67 degree

Intensity after second polarisation

= .846 I₀ cos²67 =  .13 I₀ .

C) During chemical reaction, total mass remains the same.

This is because due to the law of conservation of mass, stating that in a chemical reaction, neither mass will be created nor destroyed. So, the total mass will not change when chemical reactions occur.
