What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. The more mass an object has, the more inertia it possesses.

Front

How does mass affect inertia?

Back

An object with greater mass has more inertia, meaning it will require more force to change its motion compared to an object with less mass.

Front

What is average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken.

Front

What is a mixture?

Back

A mixture is a combination of two or more substances that are not chemically bonded, such as air or a salad.

Front

What is a chemical change?

Back

A chemical change occurs when substances combine or break apart to form new substances, often accompanied by energy changes.

Front

What is a physical change?

Back

A physical change is a change in the form or appearance of a substance without altering its chemical composition, such as melting or freezing.

Front

What is constant speed?

Back

Constant speed means moving at the same distance over equal intervals of time, without speeding up or slowing down.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, which can occur when an object speeds up, slows down, or changes direction.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is an example of a compound?

Back

A compound is a substance formed when two or more elements are chemically bonded together, such as water (H2O) or carbon dioxide (CO2).
