First law: When viewed in an interial inference frame, an object either is at rest or moves at a constant velocity, unless acted upon by an external force.

Second law: The acceleration of a body is directly proportional to, and in the same direction as, the net force  acting on the body, and inversely proportional to its mass.

Third law: When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction to that of the first body.

The coin drops straight into the glass! Place the card on top of the glass. Make sure there is enough space to give one edge of the card a good flick without smacking your finger on the glass. Ouch! Place a single coin on top of the card so that it rests over the cup's opening. Flick an exposed edge of the notecard. Don't flick the card from underneath. Flick directly from the side of the card's edge. The coin drops straight into the glass! EXPERIMENT 1: FIRST LAW

Fill the large drinking glass about three-quarters full with water. EXPERIMENT 2: Fill the large drinking glass about three-quarters full with water. Center a pie pan on top of the glass. Place the cardboard tube on the pie plate, positioning it directly over the water. Carefully set the egg on top of the cardboard tube. With your writing hand, smack the edge of the pie pan horizontally. Don't swing up, and don't swing down! It’s important that you hit the pie pan horizontally and use a pretty solid hit, so plan on chasing the plate and tube. Your astonished guests will watch the egg plop nicely into the water. It’s even more fun to watch someone else try to drop the egg. Science is so cool!

SECOND LAW EXPERIMENT #1 Put several spoonfuls of flour in the bottom of the pan and spread it out to make a level surface. Then sprinkle a thin layer of hot chocolate mix on top of the flour. Now hold one marble/rock above the surface of the flour and drop it. Do the same with the other two marbles/rocks. Now carefully lift each marble/rock out of the flour and look at the impact crater. Which marble/rock made the widest impact crater? Which one made the deepest impact crater?

EXPERIMENT 2: Cut a piece of string or thread 110 cm long .Tie a small loop in one end of the string . Make small ball of clay with a mass of about 2.25g. Attached this ball of clay around the loop. The loop will prevent the clay ball from falling off the string. Divide the remaining clay into 40g pieces. Use your balance to measure the mass of toy car. Use a meter stick to find a spot on the table 1 m from the edge. Mark it with a small piece of tape. This spot will be the starting point for the toy car during the experiment. Put the front of the toy car at the starting point. Hold the piece of string on the table so that the clay ball is about 3 cm over the edge. Tape the other end of the string to the front of the toy car. Trim any excess string so that it does not interfere with the cars wheels. Pick someone in your group to be the timer, someone to be the recorder, someone to hold the toy car in place and release it, and someone to catch it as it falls off the table. Release the car. Use a stopwatch to measure the time it takes for the car to reach the table edge. Write the travel time in table 1. Repeat steps and 9 two or more times. Use the data to calculate the average travel time for the car. Add one 40g piece of clay to the top of the car. Be careful that the clay does not interfere with the cars ability to roll freely. Time three trips of the car. Record the travel times, calculate the average time, and record the average time, and record the average time in table 1. Repeat steps 11 and 12 until you have times the car carrying 160g of clay.

THIRD LAW EXPERIMENT 1 : Couple two spring balances A and B as shown in the figure. When we pull the balance B both the balances show the same reading indicating that both the action and reaction forces are equal and opposite. In this case, the pull of either of the two spring balances can be regarded as action and that of the other balance as the reaction.

EXPERIMENT 2: Even though the action and reaction forces are equal and opposite their resultant is not equal to zero as the action and reaction forces are acting on two different bodies The third law holds good when the interacting bodies are at rest or in motion
