motion

What is a reference point in relation to the position of an object?

• The ending point of an object's position

• The starting point to describe the location of an object

• The midpoint of an object's position

• The highest point of an object's position

How is an object's position determined in 2 dimensions?

• By observing the color of the object

• By choosing a reference point and specifying directions

• By measuring the weight of the object

• By counting the number of objects around it

What is displacement in relation to motion?

• The process of changing position

• The total distance an object travels in a given amount of time

• The difference between the initial and final position of an object

• The speed and direction of a moving object

What does a graph show in relation to motion?

• The color of the object

• The shape of the object

• How an object's position changes during each time interval

• The weight of the object

The starting point you choose to describe the location, or position of an object

• Reference Point

• Distance

• Displacement

• Position

An object's distance in a certain direction from a reference point

• reference point

• distance

• displacement

• position

Motion is:

• the starting point you choose to describe the location, or position of an object

• an object's distance in a certain direction from a reference point

• the process of changing position

• how far an object moves

What is happening at A?

• Stationary
• Accelerating
• Slower steady speed; moving away from the starting position
• Steady speed; returning to start position

What is happening at B?

• Stationary
• Accelerating
• Slower steady speed; moving away from the starting position
• Steady speed; returning to start position

What is happening in this graph from point A to B?

• The object is accelerating.
• The object is not moving.
• The object is decelerating.
• The object is moving at a constant speed.
