Review Quiz #5 Sci. Variables

What is the definition of displacement?

• The total distance an object covers

• The change in position of an object compared to its starting position

• The speed and direction of an object

• The force required to move an object

What is the difference between speed and velocity?

• Speed refers to the total distance an object covers, while velocity refers to the change in position of an object

• Speed refers to the force required to move an object, while velocity refers to the total distance an object covers

• Speed refers to both speed and direction, while velocity refers to how fast something is moving

• Speed refers to how fast something is moving, while velocity refers to both speed and direction

What is the formula for calculating speed?

• S = d * t

• V = d/t

• V = d * t

• S = d/t
