Newton's Laws

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

Define inertia in the context of Newton's First Law.

Back

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

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. This is often expressed as F=ma.

Front

Explain the relationship between force, mass, and acceleration.

Back

Force is the product of mass and acceleration. If the mass increases, the acceleration decreases for a given force.

Front

What is Newton's Third Law of Motion?

Back

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

Front

Provide an example of Newton's Third Law in everyday life.

Back

When you push against a wall, the wall pushes back with an equal force in the opposite direction.

Front

What is the concept of net force?

Back

Net force is the vector sum of all the forces acting on an object. It determines the object's acceleration.

Front

How does friction affect motion according to Newton's Laws?

Back

Friction is a force that opposes motion, affecting the net force and thus the acceleration of an object.

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

Define momentum and its formula.

Back

Momentum is the product of an object's mass and its velocity, expressed as p = mv.
