What is the difference between distance and displacement?

• Distance is the total length of the path traveled in a specific direction, while displacement is the shortest distance from the initial to the final position.

• Distance is the total length of the path traveled, while displacement is the shortest distance from the initial to the final position in a specific direction.

• Distance is the shortest distance from the initial to the final position, while displacement is the total length of the path traveled.

• Distance is the displacement in a specific direction, while displacement is the total length of the path traveled.

A car travels 50 meters north, then 30 meters south. What is the total displacement of the car?

• 80 meters north

• 10 meters south

• 20 meters north

• 50 meters north

If an object covers a total distance of 50 meters in 10 seconds, what is its average speed?

• 5 m/s

• 10 m/s

• 15 m/s

• 20 m/s

A car accelerates from 20 m/s to 40 m/s in 5 seconds. What is its acceleration?

• 10 m/s^2

• 2 m/s^2

• 4 m/s^2

• 6 m/s^2

What is the formula to calculate acceleration?

• a = v * t / u

• a = (v + u) * t

• a = (v - u) / t

• a = v / (t - u)

A car starts from rest and reaches a speed of 30 m/s in 6 seconds. What is its acceleration?

• 10 m/s^2

• 3 m/s^2

• 5 m/s^2

• 20 m/s^2

How does acceleration affect an object's motion?

• It changes the object's speed and/or direction.

• It makes the object invisible

• It has no effect on the object's motion

• It causes the object to shrink in size

If an object moves at a constant speed of 20 m/s for 10 seconds, what is the total distance traveled?

• 200 m

• 10 m

• 20 m

• 2 m

A ball accelerates from 5 m/s to 15 m/s in 3 seconds. What is its acceleration?

• 3.33 m/s^2

• 10 m/s^2

• 20 m/s^2

• 5 m/s^2

A cyclist covers 40 kilometers with an average speed of 20 km/h. How long did the journey take?
