Front

What is inertia?

Back

Inertia is the tendency of an object to resist a change in its motion. The greater the mass of an object, the greater its inertia.

Front

What is mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms. Objects with greater mass have greater inertia.

Front

What is a balanced force?

Back

A balanced force occurs when two forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.

Front

What is a dependent variable?

Back

A dependent variable is the variable that is measured in an experiment. It is affected by changes in the independent variable.

Front

What is an independent variable?

Back

An independent variable is the variable that is changed or controlled in an experiment to test its effects on the dependent variable.

Front

Example of a balanced force:

Back

An asteroid moving at a constant speed through space is an example of a balanced force.

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s).

Front

What is the relationship between mass and inertia?

Back

Objects with greater mass have greater inertia, meaning they resist changes in their motion more than objects with less mass.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is the effect of friction on motion?

Back

Friction is a force that opposes motion between two surfaces in contact. It can slow down or stop moving objects.
