What is uniform linear motion?

What is uniform linear motion?

"Linear motion means that an object moves along a straight line. "Uniform" simply means that the acceleration is 0 throughout the motion."(1)

What is the difference between distance and displacement?

What is the difference between distance and displacement?

What about the velocity?

Think/Pair/Share

Crumple & Shoot

1. Create teams of 4 people and choose a name. 2. Each team will be given a piece of paper to answer a question. 3. The question will be shown in the screen. 4. You will have 30 seconds to answer the question. Once the time is finished, you have to raise the paper with the answer. 5. If your team have a correct answer, the person that held up the paper will line up to shoot to the can. 6. If the member hits the shot, one point is added to the score.

Question 1/5

An object travels in uniform linear motion from a point A to a point B located 30 meters away in 15 seconds. What is the velocity of this object?

a. 4 m/s b. 2 m/s c. 4 m/(s^2) d. 1 m/s e. 5 m/s

Question 2/5

If an object moves 14 meters to the right from its origin, and then it moves 12 meter to the left, what is the magnitude of its diplacement, measured from the origin?

a. 26 m b. 4 m c. 3 cm d. 2 m e. 1 m

Question 3/5

What is the difference between distance and displacement?

Question 4/5

What is the magnitude of the acceleration in uniform linear motion?

Question 5/5

How long would it take to an object to move from its origin, to a point P located 50 meters away, if the object is traveling in uniform linear motion with a velocity of 5 meters per second?

a. 2 s b. 7 s c. 3 s d. 8 s e. 10 s
