Science Midterm UMS review

Front

How can you describe the elements on period 3 from left to right?

Back

Elements go from metals to metalloids to non-metals.

Front

What are balanced forces?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What is the appearance of metalloids?

Back

Metalloids typically have a metallic-gray appearance and exhibit properties of both metals and nonmetals.

Front

What happens to an object when balanced forces act on it?

Back

The object remains at rest or continues to move at a constant velocity.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

What describes the motion of an object with constant speed?

Back

An object with constant speed does not accelerate; it maintains the same speed over time.

Front

What is a subatomic particle?

Back

A subatomic particle is a particle smaller than an atom, such as protons, neutrons, and electrons.

Front

What is the charge of a neutron?

Back

A neutron has no charge.

Front

Where are metalloids located on the periodic table?

Back

Metalloids are found along the zig-zag line between metals and nonmetals.

Front

What is the role of friction in motion?

Back

Friction opposes the motion of an object, causing it to slow down or stop.
