Newton's Laws of Motion Concepts

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 at a constant velocity unless acted upon by a net external force.

Front

Define 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 net force?

Back

Net force (F_net) = 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

Define mass in the context of Newton's Laws.

Back

Mass is a measure of the amount of matter in an object, which determines the object's resistance to acceleration when a force is applied.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass (Weight = mass × gravity).

Front

How do you calculate weight?

Back

Weight (W) = mass (m) × acceleration due to gravity (g).

Front

What is the significance of a free-body diagram?

Back

A free-body diagram visually represents all the forces acting on an object, helping to analyze the net force and motion.

Front

What does it mean for an object to be in equilibrium?

Back

An object is in equilibrium when the net force acting on it is zero, resulting in no acceleration.
