Newton's Laws Of Motion Lab Report

: As you can see that the greater the amount of pennies were added at the top of the cup, the shorter the distance of the cup moved and it included all of the three Newton’s laws. My hypothesis actually turned out to be accurate. It’s really fascinating that how only 1 experiment can prove all of Newton’s three laws of motion just like that. When the marble was getting released from the ramp I observed it hitting the cup and surprisingly the cup didn’t fall off or changed directions it went in a straight path. For 1 penny we got the longest distance such as 4cm for trail 1, 4.3cm for trial 2, and 5.3cm for trial 3 (the highest distance from all the trial in the experiment). For 2 pennies we got 2.8cm for trial 1, 3cm for trial 2, and 2.8cm
For 3 pennies we got 2.2cm for trial 1, 2.5cm for trial 2, and 2.6cm for trial 3 which in average was 2.4cm. For 5 pennies (the most amount of pennies/mass) we got 1.7cm for trial 1, 2cm for trial 2, and finally, 2.1cm for trial 3. Since we already could see a pattern in the results which is a decrease of the distance as more pennies/mass is added, experimenting with 4 pennies wasn’t necessary. In my graph, I realized that there was quite a drop in the line from the distance of 1 penny to 2 pennies. The line looked quite symmetrical on both sides. It looked like a boomerang. Now from the results, we can conclude that Newton’s three laws are proven to be accurate and that every action really does have an equal and opposite
If an external force is applied, the velocity will change because of the force.2The object will act to the stronger force and in this case, the cup had a stronger force than the force the marble had from accelerating which created net force and caused the marble to stop. The second law explains how the velocity of an object changes when it is subjected to an external force. The law defines force to be equal to change in momentum (mass times velocity) per change in time.2 Momentum is a physics term; it refers to the quantity of motion that an object has.4 Newton’s 3rd law isn’t only true in the scientific world but in life. For every action, there is an equal amount of opposite reaction. The statement actually means that in every interaction, there is a pair of forces acting on the two interacting objects.3The size of the forces on the first object equals the size of the force on the second object (which explains the equal part in the law). The direction of the force on the first object is opposite to the direction of the force on the second object (which explains the opposite reaction
