What is the difference between distance and displacement?

• Distance is a scalar quantity and displacement is a vector quantity.

• Distance is always greater than or equal to displacement.

• Distance can be zero, but displacement cannot be zero.

• Distance is the path length between two points, while displacement is the difference between starting and ending points.

What is the term for total distance traveled divided by the total time taken to travel that distance?

• average speed

• average velocity

• instantaneous speed

• acceleration

When referring to velocity, what does the length of the arrow represent?

• the speed

• the direction

• the mass

• the time

For acceleration to occur, what must take place?

• speed up, slow down, or change direction

• remain at constant speed

• stay stationary

• move in a straight line at constant speed

Define constant speed.

• the rate of change of position in which the same distance is traveled each second

• the rate of change of position in which different distances are traveled each second

• the rate of change of position in which the speed varies over time

• the rate of change of position in which acceleration is constant

What does a speed-time graph tell you about an object’s motion?

• The speed of the object at any given time

• The distance covered by the object

• The acceleration of the object

• The direction of the object's motion

How can you use an object’s velocity and the time it takes to travel a certain distance to determine its acceleration?

• By dividing the velocity by the time

• By multiplying the velocity by the time

• By subtracting the initial velocity from the final velocity and dividing by time

• By adding the velocity and time

What is the term for the difference between the initial and final position of an object?

• Distance

• Displacement

• Velocity

• Acceleration
