In a motion graph, what does a closer spacing of points indicate?

• The object is moving faster

• The object is moving slower

• The object is stationary

• The object is accelerating

What does a motion graph represent?

• The speed of an object at different times

• A series of points indicating an object's position at one-second intervals

• The acceleration of an object over time

• The distance traveled by an object in one second

How is acceleration represented on a motion graph?

• Points are evenly spaced

• Points are decreasing in distance apart

• Points are increasing in distance apart

• Points are clustered together

In the equation , y = mx + b , what does the 'b' represent?

• Slope

• Y-intercept

• X-intercept

• Rise

What does the slope of a position vs. time graph represent?

• Acceleration

• Velocity

• Displacement

• Time

If the initial position $ x_0 $ is 400 m and the slope of the graph is constant, what is the formula for position $ x $ at any time $ t $?

• $ x = x_0 + vt $

What does a zero slope indicate in a position vs. time graph?

• Moving away from the starting point

• Moving towards the starting point

• Not moving

• Changing direction

What happens when the slope changes sign in a position vs. time graph?

• The object accelerates

• The object changes direction

• The object stops

• The object moves faster

What does a downward sloping straight line on a position vs. time graph indicate?

• Constant velocity, positive direction

• Constant velocity, negative direction

• Changing velocity, positive direction

• Changing velocity, negative direction

What does a curve that slopes downward on a position vs. time graph indicate about velocity?

• Positive velocity, slow to fast

• Negative velocity, slow to fast

• Positive velocity, fast to slow

• Negative velocity, fast to slow
