Final Review

Front

What is constant positive velocity?

Back

Constant positive velocity refers to an object moving in a straight line at a steady speed in a positive direction, meaning its speed does not change over time.

Front

What is inertia?

Back

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

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity. It is a vector quantity, meaning it has both magnitude and direction.

Front

What is the formula for calculating force?

Back

Force (F) is calculated using the formula F = m * a, where m is mass and a is acceleration.

Front

What is the relationship between force and acceleration?

Back

According to Newton's second law, force is directly proportional to acceleration. If the mass remains constant, doubling the acceleration will double the force.

Front

What is global warming?

Back

Global warming refers to the long-term increase in Earth's average surface temperature due to human activities, primarily the emission of greenhouse gases.

Front

What are greenhouse gases?

Back

Greenhouse gases are gases that trap heat in the atmosphere, contributing to the greenhouse effect. Examples include carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).

Front

What is the effect of electric vehicles on global warming?

Back

Electric vehicles help reduce global warming by decreasing reliance on fossil fuels, thus lowering greenhouse gas emissions.

Front

What is the momentum of an object?

Back

The momentum of an object is calculated as the product of its mass and velocity (p = m * v).

Front

What happens to momentum when mass increases while velocity remains constant?

Back

If the mass of an object increases while its velocity remains constant, its momentum increases proportionally to the increase in mass.
