100
Using this 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
Make the best reference points to determine motion.
What are stationary objects?
200
You take the difference of these two things and divide it by the time.
What is the final speed minus the initial speed.
200
Unit of force in SI units
What is the newton?
200
The difference between sliding and rolling friction.
What is rolling requires wheels (or spheres)?
200
According to this law acceleration depends on the objects mass and on the net force ating 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 acceeleration 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 ush together and the type of surface involved?
300
When a car applies its breaks 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 a 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 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 movement?
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 that states that in the absence of outside forces, the total momentum of objects that interact does not change.
What is the Law of conservaion of momentum
