What is force?
A push or pull that acts on an object.
100
If 20N of force are pushing to the left and 20N of force are pushing to the right, which way will the box move?
Neither way. It is a balanced or net zero force.

Two friends are playing tug-of-war with a rope. Both pull with equal strength, but the rope does not move in either direction. What is the reason for the rope's lack of movement?
The force of friction

A. Balanced forces

B. The force of gravity

C. Unbalanced forces

D. The force of friction 


What is A. Balanced Force

What is Newton's 3rd Law of Motion?
For every action there is an equal and opposite reaction.
200

What is an unbalanced force?

forces acting on an object that combine and form a net force that is not zero

200
If someone is pushing with 50N of force to the right and the other person is pushing with 10N of force to the left, which way will the box go?
To the right, because there is more force pushing that way.

What would happen to a vase of flowers if you rapidly pulled the tablecloth from under them?
They would remain standing.

Which of the following scenarios best illustrates Newton's third law of motion?


A. A car accelerates forward as the engine exerts a force on the wheels.

B.A swimmer pushes water backward to move forward in the pool.

C. A rocket launches upward as gases are expelled downward.

D.A cyclist pedals harder to increase speed on a flat road.


C. the rocket launches upward as gases are expelled downward.

300
What is friction?
A force that acts against moving objects.
300
If Spongebob was pushing a crabby patty to the left and plankton was pushing it to the right, which way would it go and why?
To the left, because Spongebob is bigger and stronger than plankton.
300
What happens to the speed of a little worm, if it is required to pull a large apple?
It goes slower.
300

Which of the following does NOT represent a force pair?

A.When you pull on the rope in tug-of-war, your opponent pulls on the other side of the rope.

 B.When a diver jumps off a diving board, the board pushes the diver up.

 C.When an ice skater pushes off a wall, the wall pushes the skater off the wall.

 D.When a boy pulls a wagon, the wagon pulls back on the boy.

A.When you pull on the rope in tug-of-war, your opponent pulls on the other side of the rope.

Think back to our experiments that were conducted in class, how was the care attached to the balloon able to move forward? What caused it to move?

The air that the balloon pushes out when it deflates 

400
What is gravity?
A force that pulls objects to the Earth.
400
If two people are pushing a box to the right and each person is putting forth 20N of force. Which way will the box move and with how much force will it be moving?
To the right with 40N worth of force.
400
What happens to the speed of a big worm, if it only has to pull a tiny apple?
It goes faster.

Why does a person diving from a high board need to adjust their body position more than someone stepping into the pool?

A.  The diver's initial speed is greater, increasing the impact force.

B. Stepping into the pool allows for a slower descent.

C.Divers have a streamlined shape that increases speed.

D.Water resistance is less effective on a diving body.


A.  The diver's initial speed is greater, increasing the impact force.

What are balanced forces?

forces acting on an object that combine and form a net force of zero.

500
If Ms. Cibasek was pushing a box to the left and Mr. Abu-Rus was pushing a box to the right, which way would the box go?
To the right, because Mr. Abu-Rus is pushing with more strength and force than Ms. Cibasek (Ms. Cibasek is still awesome though!)
