Newton's Three Laws of Motion and Free Fall 2025

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

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

Define velocity.

Back

Velocity is the speed of an object in a specific direction.

Front

What is the formula for calculating force?

Back

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

Front

What is free fall?

Back

Free fall is the motion of an object under the influence of gravitational force only.

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, proportional to their masses and inversely proportional to the square of the distance between their centers.

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, calculated as weight (W) = mass (m) × gravitational acceleration (g).

Front

What is inertia?

Back

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

Front

What is the effect of mass on acceleration according to Newton's Second Law?

Back

As mass increases, acceleration decreases for a given force.
