Distance, Displacement, and Velocity Concepts

This video tutorial introduces key physics concepts such as length, displacement, speed, velocity, and acceleration. It explains the differences between distance and displacement, and how to perform metric conversions. The tutorial also covers how to interpret distance vs. time and velocity vs. time graphs, including calculating speed and acceleration.

What is the standard unit for measuring length?

• Feet

• Yards

• Meters

• Inches

How is displacement different from distance?

• Displacement is always greater than distance.

• Displacement is the straight line from start to end.

• Displacement is the total path traveled.

• Displacement is measured in time.

In which scenario would distance and displacement be equal?

• Walking in a circle

• Running on a zigzag path

• Traveling in a straight line without turning back

• Climbing up and down a hill

How many millimeters are there in one meter?

• 10000

• 1000

• 10

• 100

Convert 7.9 kilometers to meters.

• 790 meters

• 7900 meters

• 79000 meters

• 79 meters

What is the average speed if a ball travels 5 meters in 1.5 seconds?

• 3.33 meters per second

• 5 meters per second

• 1.5 meters per second

• 2.5 meters per second

What does the slope of a distance vs time graph represent?

• Velocity

• Time

• Acceleration

• Displacement

What is the velocity at 7 seconds on a velocity vs time graph?

• 30 meters per second

• 40 meters per second

• 50 meters per second

• 60 meters per second

When is an object decelerating on a velocity vs time graph?

• When the slope is constant

• When the slope is negative

• When the slope is zero

• When the slope is positive

Calculate the acceleration if the final velocity is 2.3 m/s, initial velocity is 1.2 m/s, over 5 seconds.

• 0.44 m/s²

• 0.66 m/s²

• 0.22 m/s²

• 0.88 m/s²
