8vo S3 Positions of Objects

What are the two properties of physical quantities?

• speed and direction

• magnitude and unit

• distance and mass

• temperature and numbers

How do we classify physical quantities? (choose two)

• fundamental

• derived

• magnitudes

• units

A change in the position of an object with respect to a fixed point in a period of time.

• Speed

• Velocity

• Movement

• Stationary

Why is movement relative?

• It depends on the size of the object that is in motion.

• It depends on the movement of the object in motion.

• It depends on the visual ability of the observer.

• It depends on the positions of the observers.

Point or group of points that we use to determine if a body is moving.

• Force

• Distance

• Frames of Reference

• Position

The amount of matter that a body has.

• mass

• weight

• force

• gravity

The progressive increase of velocity of an object.

• force

• mass
