What is Newton's first law?
Every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force
What is an unbalanced force?
A force that is moving.

If you and your sibling are playing tug of war. Your sibling is pulling with a force of 10 N and you are pulling in the opposite direction at 15 N. Who is going to win and what is the net/total force?
You are going to win and by 5N.
How do you find Newton's second law?
F=M*A
What is a Force?
A force is a push or a pull.
Out of a 100 what is the level of potential energy that is present in a roller coaster all the way up at the top of the tallest hill.
100% potential energy
Out of a 100 what is the level of potential and kinetic energy that is present in a roller coaster that is halfway down the hill?
50:50
Austin gets upset for loosing again at Kahoot and attempts to break his pencil in half. He tries and tries, but it's just too strong. Finally, Heidi feels sorry for him and karate chops the pencil he is holding in his hand. She applies a 50 N force to the left, while Austin's stationary hand applies a 43 N force to the right.
7 Newtons
What is Newton's 3rd law of motion?
For every action there is an equal and opposite reaction.
What is the force that pulls you down to Earth?
Gravity.
Name all potential energy types.
Chemical, Elastic and Gravitational potential.
Name all types of kinetic energy types.
Sibling 1 and Sibling 2 are working together against their older sibling. Sibling 1 is pulling with a force of 12 N and Sibling 2 is helping pull with a force of 15 N. The older sibling is stronger and can pull a force of 21 N. What is
12N + 15 N= 27N
27N - 21N= 6 N
Sibling 1 and Sibling 2 wins by 6 N
If a 6kg bowling ball is rolled down the bowling lane with a force of 12 N.What is the acceleration of the bowling ball?
F=M*A or A=F/M
12N/6kg=
A=2 m/s2
What is the force that goes against you and slows you down.
Friction force.
