motion and force

What is the difference between distance and displacement?

• • Distance is the change in position of an object, and displacement is the total path traveled.

• • Distance is scalar, while displacement is a vector.

• • Distance is a vector, while displacement is scalar.

• • Distance includes direction, while displacement does not.

If a car travels 60 meters in 5 seconds, what is its speed?

• 10 meters per second
• 12 meters per second
• 15 meters per second
• 20 meters per second

What is acceleration?

• Acceleration is the force applied to an object.
• Acceleration is the distance traveled over time.
• Acceleration is the rate of change of velocity over time.
• Acceleration is the speed of an object.
