What is the term for when an object changes its position?

• Reference point

• Distance

• Motion

• Displacement

What is a reference point?

• The distance an object has moved

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

• The change in position of an object

• The speed of an object

How is distance defined in the context of motion?

• The speed of an object

• The time taken to move

• How far an object has moved

• The direction of movement

What does displacement refer to?

• The total path traveled by an object

• The speed of an object

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

• The time taken to move

What is the definition of speed?

• The distance an object travels per unit time

• Total distance traveled divided by total time traveled

• Speed at a given point in time

• Speed of an object and the direction of its motion

How is average speed calculated?

• By measuring the speed at a given point in time

• By dividing total distance traveled by total time traveled

• By considering the direction of motion

• By multiplying speed and time

What does instantaneous speed refer to?

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

• The distance an object travels per unit time

• Speed at a given point in time

• Total distance traveled divided by total time traveled

What is velocity?

• The distance an object travels per unit time

• Total distance traveled divided by total time traveled

• Speed at a given point in time

• Speed of an object and the direction of its motion

What is the definition of force?

• A push or pull one body exerts on another

• The sum of all forces acting on an object

• The tendency of an object to resist a change in its motion

• A force that resists a change in motion caused by two objects in contact

What does net force refer to?

• A push or pull one body exerts on another

• The sum of all forces acting on an object

• The tendency of an object to resist a change in its motion

• A force that resists a change in motion caused by two objects in contact
