Newton's Laws Review

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is the law of conservation of mass?

Back

Mass is neither created nor destroyed in a chemical reaction; it is conserved.

Front

What is normal force?

Back

The force exerted by a surface to support the weight of an object resting on it, acting perpendicular to the surface.

Front

What is friction?

Back

Friction is the force that opposes the motion of an object in contact with a surface.

Front

What is the difference between static and kinetic friction?

Back

Static friction prevents motion between two surfaces, while kinetic friction acts on moving objects.

Front

What is the law of universal gravitation?

Back

Every point mass attracts every other point mass in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
