May the Force Be With You
This type of force occurs when equal sizes push in opposite directions, resulting in 0 N of net force and zero movement.
What is a balanced force?
These are the two essential "parts" you need to identify an object's velocity.
This Law, also known as the Law of Inertia, explains why you keep sliding forward when a car suddenly slams on the brakes.
What is Newton's First Law?
This specific type of friction involves air or water; it's also why skydivers use parachutes.
What is fluid friction?
Ca
What is Calcium?
To find the net force of two people pushing a stalled car in the exact same direction, you should perform this mathematical operation.
What is addition?
How do we calculate average speed?
What is total distance divided by total time?
Newton’s Second Law is summarized by this three-letter mathematical formula.
What is F = m x a
Of the four types of friction, this one is the "laziest" because it acts on objects that aren't moving at all.
What is static friction?
Xe
What is Xenon?
This is the specific term for a fixed object or place used to determine if something else is actually in motion.
What is reference point?
On a Distance-Time graph, you can tell an object is accelerating because the line looks like this, rather than a straight diagonal.
What is a curved line?
This law explains how a bird flies: its wings push the air down (action), and the air pushes the bird up (reaction).
What is Newton's Third Law?
To turn sliding friction into this "easier" type of friction, you might add wheels or ball bearings to a heavy box.
What is rolling friction?
Au
What is Gold?
This is a type of force that does not require direct contact between two objects
Non-Contact Force
On a Speed-Time graph, a horizontal line doesn't mean the object is stopped; it means it is traveling at this.
What is a constant speed?
According to the Second Law, if you keep the force the same but increase the mass of the object you are pushing, this will happen to the acceleration.
What is it will decrease? (harder to move)
These are the two surfaces involved when you push a book across a desk.
What is sliding friction?
Pu
Plutonium
Two children fight over a toy, one pulls with 8N to the left, one pulls with 6N to the right. What is the strength and direction of the net force?
What is 2N to the right?
How do we calculate speed from a graph?
By slope = rise/run
This is an object's tendency to resist changes in motion
What is inertia?
What is the measurement of the force of gravity on Earth?
What is 9.8 m/s^2?
Ra
Radium
