MOTION

Motion can be describe as a change in __________________.

• position

• direction

• solution

• atttraction

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

• point of comparison

• point of reference

• point of view

• none of the above

A bicycle has an average speed of 2m/s. This means that _________.

• a. in 1 second, it travels 1 meter

• b. it can travel 4 meters in 2 seconds

• c. it takes 2 seconds to travel 1 meter

• d. A car moving down a straight highway at constant speed.

How can we describe the change in position of an object?

• Determine the initial position and final position.

• Describing its direction relative to that point of reference.

• Describing how far the object is from the point of reference

• None of the above.

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

• motion

• point of reference

• distance

• displacement

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.

• motion

• point of reference

• distance

• displacement

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

• distance

• displacement

• speed

• motion

What is the formula in calculating the speed?

• S = t/d

• S = d x t

• S = t + d

• S = d/t
