Force, a push or pull
Force is like music
because it has many kinds
For example
Contact force, gravity, friction, balanced and unbalanced...
Everything must have force to move
I can prove
For example
When you are handing your friend an apple
You're using force

To find force,
You use this formula
The formula is F= ma
F is force, m is mass, and a is acceleration
Balanced force is opposite with unbalanced force
Balanced force is when there are equal forces pushing on an object
Unbalanced force is when there are unequal forces pushing on an object.

State of Tennis

Opinion about tennis

    I think tennis is a very good sport because it helps me to run faster and also stronger because when you serve, if you want your serve to be strong, you need to push up a lot. How it helps me run faster is I have to hit the ball the other side in one bounce but I can’t let the ball bounce twice or you will be losing points.
