Key Term & It's Proper Usage

Key Term

• Distance: is how much an object has travel, and some might interpret distance as the space between two objects to one another

• Displacement: is how much an object has travel compare to its initial position

• Speed: is the rate at which an object can move or currently moving

• Velocity: is the speed of something in a given direction

• Acceleration: is the increase of rate in a moving object

• Deceleration: is the decrease of rate in a moving object

Example in Real Life:

Thomas runs 500 m every day at 5 O’clock in the afternoon from his house to a market.  And directly come back home before even entering the market.  He runs 5 m/s always, until he can see the market from his eyes. Then Thomas accelerate 3 m/s^2. When he is on his way back home he decelerates until 6 m/s.

Answer:

Distance: 1000 m

Displacement: 0 m

Velocity: at first: 5 m/s

      On the way back: 6 m/s

Acceleration: 3 m/s^2

Deceleration: 2 m/s^2
