Midterm Physical Science Quiz

What is the definition of motion?

• when an object changes its position

• an indicator that orients you; the place you measure, record, or witness an event

• how far an object has moved

• distance and direction of an object's change in position; difference from starting to ending point

What is the definition of reference point?

• when an object changes its position

• an indicator that orients you; the place you measure, record, or witness an event

• how far an object has moved

• distance and direction of an object's change in position; difference from starting to ending point

What is the definition of distance?

• when an object changes its position

• an indicator that orients you; the place you measure, record, or witness an event

• how far an object has moved

• distance and direction of an object's change in position; difference from starting to ending point

What is the definition of displacement?

• when an object changes its position

• an indicator that orients you; the place you measure, record, or witness an event

• how far an object has moved

• distance and direction of an object's change in position; difference from starting to ending point

What is the definition of speed?

• the distance an object travels per unit of time

• total distance traveled divided by the total time travelled

• the speed of an object at any given point

• the speed of an object and the direction of its motion
