What is Newton's Second Law of Motion?

Back

It states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is a force?

Back

A push or pull that is exerted on matter.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What does it mean when we say 'for every action, there is an equal and opposite reaction'?

Back

This is Newton's Third Law of Motion, which means that for every force exerted, there is a force of equal size but in the opposite direction.

Front

What is the formula for calculating force?

Back

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

Front

What is the relationship between mass, force, and acceleration?

Back

Newton's Second Law of Motion explains that the acceleration of an object depends on the mass of the object and the amount of force applied.

Front

What is an example of Newton's First Law of Motion?

Back

A soccer ball remains at rest until a player kicks it.

Front

What happens when a student pushes against a wall with 20 N of force?

Back

The wall exerts an equal and opposite force of 20 N back on the student.

Front

What is an example of inertia in everyday life?

Back

A passenger lurching forward in a car when it suddenly stops.

Front

What is the effect of friction on motion?

Back

Friction opposes the motion of an object, slowing it down or stopping it.
