Newton's Laws of Motion

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 a net external force.

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 Newton's Third Law of Motion?

Back

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

Front

How does mass affect acceleration when a constant force is applied?

Back

If the mass of an object is increased while the force remains constant, the acceleration decreases.

Front

What is the formula for calculating weight?

Back

Weight (W) is calculated as W = mg, where m is mass and g is the acceleration due to gravity.

Front

What is the coefficient of friction?

Back

The coefficient of friction is a dimensionless scalar value that represents the ratio of the force of friction between two bodies and the force pressing them together.

Front

What is static friction?

Back

Static friction is the frictional force that prevents two surfaces from sliding past each other when a force is applied.

Front

What is kinetic friction?

Back

Kinetic friction is the frictional force that opposes the motion of two surfaces sliding past each other.

Front

What is air resistance?

Back

Air resistance is a type of friction that acts against the motion of an object moving through the air.

Front

How do mass and weight differ?

Back

Mass is a measure of the amount of matter in an object, measured in kilograms, while weight is the force exerted by gravity on that mass, measured in newtons.
