Newton's 3 Laws of Motion
100
Using this point you can tell an object is in motion
What is a reference point?
100
The rate at which the velocity of an object changes
What is acceleration?
100
A push or a pull
What is a force?
100
Friction which occurs when a solid moves through either a liquid or a gas.
What is fluid friction?
100
Also called the law of Inertia
What is newton's first law of motion?
200
best reference points to determine motion.
What are stationary objects?
200
On a time versus distance graph, this is a straight diagonal line.
What is constant speed?
200
Unit of force in SI units
What is the newton?
200
The difference between sliding and rolling friction. (What does one require that the other does not.)
What is rolling requires wheels (or spheres)?
200
According to this law, acceleration depends on the object's mass and on the net force acting on the object.
What is Newton's second law of motion?
300
To calculate the speed of an object you need to know these two things
What are the distance( traveled) and the time ( it took to get there)?
300
In science, acceleration refers to these three things:
What is increasing speed, decreasing speed or changing direction?
300
Unbalanced forces always cause this
What is motion?
300
The strength of the force of friction depend on these two factors.
What is how hard the surfaces push together and the type of surface involved?
300
When a car applies it's brakes quickly, your body keeps going even if the car stops exhibits this law of motion.
What is Newton's first law?
400
When you know both the speed and the direction, you know this.
What is velocity?
400
A race car's acceleration if its speed changes from 0 m/s to 40 m/s in 4 seconds.
What is 10 meters per second squared?
400
Equal forces acting on one object in opposite directions is called ______ ________ .
What are balanced forces?
400
Air resistance is this type of friction.
What is fluid friction?
400
For every action there is an equal but opposite reaction. ( Which law?)
What is Newton's Third Law of motion?
500
Using a graph you can show motion using these two variables on the x and y axis.
What is distance on the y and time on the x ?
500
Two objects traveling at the same speed have different velocities if.
What is they are moving in different directions?
500
Balanced forces never cause.
What is motion?
500
The difference between mass and weight?
What is mass is the amount of a substance, weight is the force of gravity on an object.
500
The law states that any two objects in the universe that have mass attract each other.
What is the Law of universal gravitation?
