Newton's Laws of Motion

Front

What is Newton's First Law of Motion?

Back

An object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by an unbalanced force.

Front

What is 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 force?

Back

Force (F) = 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

What is the role of gravity in motion?

Back

Gravity is a force that attracts two bodies towards each other, affecting their motion and orbits.

Front

What is terminal velocity?

Back

Terminal velocity is the constant speed an object reaches when the force of gravity is balanced by the drag force acting against it.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change an object's motion, while unbalanced forces cause an object to accelerate.

Front

What is an example of an unbalanced force?

Back

A car accelerating when the driver presses the gas pedal.

Front

How does mass affect gravitational force?

Back

The greater the mass of an object, the greater the gravitational force it exerts.
