2. Newton’s 3 Law of Motion.
1st Law of motion: The first law states that the object will tend to rest unless a force can cause it to move
2nd Law of motion: The second law states that the acceleration of an object depends on the force and the mass of the object
3rd law of motion: The third law of motion states that for every action there is a equal or opposite reaction.

3. Soccer
1st law of motion: The ball will not move unless a force like the soccer player’s foot can move the ball by kicking the ball.
2nd law of motion: it depends, if the ball have a lot of mass, it will require more force. If the ball have little mass, it will require little force.
3rd law of motion: Once you kick the ball, you will feel a short pain in your foot because in every action there is a equal or opposite reaction

4. Acceleration in Soccer
Acceleration is very important in the game of soccer. It helps the player to get past the opponent easily. If the player keep improving its leg strength, he or she will have an accelerated ability to accelerate the body using their legs

5. Friction in Soccer
Friction in soccer is greatly involved in the game soccer. There are actually 4 types of friction in soccer but I will explain 1 which is very important which is the Rolling friction The rolling friction is often involved because as the soccer ball rolls across the field, rolling friction acts upon the ball and causes it to slow down and eventually making the ball to stop

6. Does mass or weight affect soccer
Yes it does. If the ball has more weight, it will be more harder to kick. The more the player weighs, the harder they can kick.

7. Tennis
1st Law of motion: When you hit the ball with your racket, it heads off in a certain direction. This is because of air resistance who slows the speed of the ball and gravity who pulls the ball toward the ground.
2nd Law of motion: The mass of the ball is constant. So the harder you hit the ball, it goes faster.
3rd law of motion: Every time you hit the ball, you must hit it with equal force and put in enough force to send in back into you opponent.

8. Acceleration in Tennis
If the player improves the leg strength in training, he or she will have increased ability to accelerate the body using the legs. Resulting in better speed and court speed.

9. Friction in Tennis
Tennis players use specially designed tennis shoes that creates traction/friction in the court. It allows to run and stop more easily

10. Does mass and weight affects tennis?
Yes it does. Because the harder the racket weighs, more speed for the ball to travel.
