SOL Review: Part 2 of Force, Motion, Energy, and Matter

Front

What is Newton's 2nd Law of Motion?

Back

Newton's 2nd Law states that acceleration is produced when a force acts on a mass. The greater the mass, the greater the force needed to accelerate the object.

Front

What is a chemical change?

Back

A chemical change is a process where substances combine or break apart to form new substances, such as ripening bananas turning yellow.

Front

What is Newton's 1st Law of Motion?

Back

Newton's 1st Law states that an object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by an external force.

Front

Is breaking glass a chemical or physical change?

Back

Breaking glass is a physical change because it alters the form of the glass but does not change its chemical composition.

Front

What is Newton's 3rd Law of Motion?

Back

Newton's 3rd Law states that for every action, there is an equal and opposite reaction, which explains how rockets work.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the mass of the object.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It occurs when an object speeds up, slows down, or changes direction.

Front

What is force?

Back

Force is a push or pull on an object that can cause it to accelerate. It is measured in Newtons (N).

Front

What is the formula for calculating force?

Back

The formula for calculating force is F = m * a, where F is force, m is mass, and a is acceleration.

Front

What is the difference between a chemical and physical change?

Back

A chemical change results in the formation of new substances, while a physical change alters the form of a substance without changing its chemical identity.
