Science 8 Semester One Test Questions

T/F--->fill in the blank

Speed is a ______ quantity

scalar

______ is the rate at which velocity changes (over some time)

acceleration

Will an object’s mass affect its momentum?

Yes, it will. P=mv

T/F: Objects with a net force of zero will move in the direction of the force.

False, They won’t move.

_______ is speed in a given direction

velocity

_______ is the change in position of an object

motion

The momentum of a 5000kg truck that is not moving is ________ the momentum of a 3000kg truck that is at rest

the same as. because P=mv and if velocity is 0 (the object isn’t moving), since anything times 0 is 0, they will both have momentum of 0.

The _________ variable is found on the y- axis

dependent

Mass * Velocity =

Momentum

Measuring a value between the points of a line is called ________

interpolation
