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 an 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 displacement in physics.

Back

Displacement is the shortest distance from the initial to the final position of an object, along with the direction.

Front

What is the formula for calculating force?

Back

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

Front

What is the role of friction in motion?

Back

Friction is a force that opposes the motion of an object, acting opposite to the direction of motion.

Front

How does mass affect acceleration according to Newton's Second Law?

Back

As mass increases, acceleration decreases for a given force.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is the significance of a constant mass in motion?

Back

A constant mass means that the acceleration of an object is directly proportional to the net force applied to it.

Front

How does the angle of a force affect its effectiveness in causing motion?

Back

The effective component of a force that causes motion is maximized when the force is applied in the same direction as the motion.
