Displacement & Velocity Graphs
This type of graph shows position on the y-axis and time on the x-axis.
What is a position-time (displacement-time) graph?
This is the definition of acceleration in terms of velocity and time.
What is the rate of change of velocity over time?
This is the SI symbol/unit used to represent force.
What is N (Newton)?
In a free body diagram, the object being studied is typically represented by this simple shape.
What is a dot or box?
This term describes forces that are equal in size and opposite in direction, resulting in no change in motion.
What are balanced forces?
On a position-time graph, this is what the slope represents.
What is velocity?
These are the SI units for acceleration.
What is meters per second squared (m/s²)?
This term describes the object that is causing/exerting a force.
What is the agent?
In a free body diagram, forces are represented using these.
What are arrows (vectors)?
This is the resulting net force when all forces on an object are balanced. (This answer is a number)
What is zero?
On a velocity-time graph, a flat horizontal line means the object is doing this.
What is moving at constant velocity?
On a velocity-time graph, this feature represents acceleration.
What is the slope?
This term describes the object or group of objects being analyzed, upon which forces act.
What is the system?
In a free body diagram, the length of an arrow typically represents this property of the force.
What is the magnitude (strength) of the force?
This term describes forces that are unequal, causing an object to accelerate.
What are unbalanced forces?
On a position-time graph, a horizontal line (zero slope) means the object is doing this.
What is being at rest (not moving)?
When an object speeds up, its acceleration is in this direction relative to its velocity.
What is the same direction?
This type of force requires physical touching between two objects, such as friction or a push.
What is a contact force?
This is the term for a diagram that only shows the forces acting ON the object, not forces the object exerts on others.
What is a free body diagram?
This is the term for the single combined force that results from adding all forces acting on an object.
What is the net force?
This is what the area under a velocity-time graph represents.
What is displacement?
When an object slows down, this term describes its acceleration?
What is deceleration (negative acceleration)?
This type of force acts at a distance without objects touching, such as gravity or magnetism.
What is a field force?
When drawing a free body diagram for an object sitting on a table, these are the two forces you must include at minimum.
What are gravity and the normal/upward force?
According to Newton's first law, an object with balanced forces acting on it will do this. [Think back to Rainah and J'Mina's demonstration in class]
What is remain at rest or continue at constant velocity?
