Newton's Laws Flashcard

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 unless acted upon by a net external force.

Front

What is the definition of inertia?

Back

The resistance of an object to changes in its state of motion.

Front

What is the correct unit for force?

Back

Newtons (N)

Front

What does Newton's Second Law of Motion state?

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 relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, calculated as weight = mass × gravity.

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 inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it resists changes in its motion more.

Front

What is the formula for calculating force?

Back

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

Front

What is the significance of the term 'net force'?

Back

Net force is the total force acting on an object after all the individual forces are combined.

Front

How does gravity affect weight?

Back

Weight varies with the strength of the gravitational field; it is greater on planets with stronger gravity.
