Newton's Laws
How many laws of motion did Isaac Newton make?
3 Laws of Motion.
What is Net Force?
What type of force is gravity. (Contact or Noncontact).
Noncotact Force
Does friction work for or against an object being slid across the floor.
Against
Electric current.
What is the law of inertia?
Newton's First Law of Motion
What are the two types of net forces?
Balanced and unbalanced
Gravity on Earth pulls all things to this.
The center of the Earth
Lucky Space!
If this is the first space you picked then add 300 points instead of 200.
The area in which electricity moves is called this.
Electric field
If I push a heavy book it will move slower than a light book even if the same amount of force is applied. This is what law of motion?
Newton's Second Law of Motion
Which type of force causes motion.
Unbalanced Forces.
Who discovered gravity?
Isaac Newton
What is the difference between rolling friction and sliding friction?
Rolling friction is slight contact with the ground while sliding friction is constant contact with the floor.
_____ forces repel and _______ forces attract.
Like;Opposite
Newton's Third Law of motion states that every action has a(n) ______ and _________ reaction.
Equal;Opposite
If I add 5 Newtons of force to a box West and my dog adds 5 Newtons of force West to the same box what is the Net Force acting on the box?
10 Newtons of Force West.
When a book is on a table why doesn't it fall if gravity is pulling against it.
The force of the table is balanced with the force of gravity.
What are the 4 types of friction (each one guessed correctly adds 100 points).
Fluid friction, rolling friction, static friction, sliding friction.
Why does a balloon rubbed in your hair stick to a wall?
The electrons shift and the balloon's charge is opposite to that of the wall. Since opposite charges attract the balloon sticks to the wall.
A rocket ship flying is an example of this law of motion.
Newton's Third Law of Motion
If I add 200 Newtons of Force South and my dog adds 98 Newtons of Force North what is the Net Force acting on the object.
102 Newtons of Force South
What 2 things lead to a change in the amount of gravity between two objects?
Mass (increases) and distance (decreases).
What would happen if we did not have friction.
We would not be able to stop moving or standing and we would all slide forever.
What moves to create electricity?
Electrons
