• Who are you??
• Don't give up so easily!
• I am Newton the Second! And I can solve any problems using a simple solution- physics! What is going on here is so simple. It's Newton's 3rd law: An action force results in a reaction force.
• Wow! I didn't know that! Thank you!!
• Judging by the amount of boxes plus the mass of the motorcycle, it is clear that the combined mass is higher than your body mass. Due to this, when you push on the boxes and cycle, it pushes back, causing you to acceleration... backwards! A solution you could use is putting the boxes in a lighter transportation object. I have another cart here with me- you can use that!
• Wait.. but I'm applying the same amount of force as you right now and my cart is still moving so slowly!! It feels like I have to push it harder just to keep up with you.
• Well... that's simple. According to Newton's second law, the higher the mass of an object, the lower the acceleration. This is because the magnitude of acceleration is proportional to the magnitude of the net force, and inversely proportional to the mass of an object. So even if we apply the same amount of force, because your cart has a higher mass than mine, your acceleration is lower.
• Wow. I've learned so much from you! Even if I'll deliver the packages late, I've been able to learn laws that will be useful to me for the rest of my life! Thank you so much!
• Of course! Physics is a wonderful thing that explains so many parts of our lives. We learn more about the world we live in everday.
