SUMMATIVE TEST IN SCIENCE 7

It refers to the length of the entire path that the object travelled.

• displacement

• distance

• speed

• velocity

It is defined as distance travelled divided by the time of travel.

• displacement

• distance

• speed

• velocity

It refers to the shortest distance between the object’s two positions, like the distance between its point of origin and its point of destination, no matter what path it took to get to that destination.

• displacement

• distance

• speed

• velocity

You can determine whether an object moves by comparing its position to that of a fixed point.

• motion

• reference

• reference point

• speed

Speed with direction is referred to as _________________.

• displacement

• distance

• speed

• velocity

It is the distance travelled over the time to cover such distance.

• average speed

• constant speed

• instantaneous speed

• instantaneous velocity

Suppose that an object travels from one point in space to another. What is the difference between the displacement and the distance traveled?

• It is either less than or equal to the distance traveled.

• The displacement is either greater than or equal to the distance traveled.

• It can be either greater than, smaller than, or equal to the distance traveled.

• If the displacement is equal to zero, then the distance traveled will also equal zero.
