Laws of Motion

Front

What is Newton's 2nd Law of Motion?

Back

Newton's 2nd Law states that Force equals Mass times Acceleration (F = m × a). It explains how the velocity of an object changes when it is subjected to an external force.

What is a force?

Back

A force is a push or a pull that can cause an object to accelerate, change direction, or change shape.

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

What is terminal velocity?

Back

Terminal velocity is the constant speed that a freely falling object eventually reaches when the resistance of the medium (like air) prevents further acceleration.

What is the formula for calculating force?

Back

Force (F) = Mass (m) × Acceleration (a).

Front

What does it mean when forces are balanced?

Back

When forces are balanced, the net force acting on an object is zero, resulting in no change in motion.

Front

What is the relationship between mass and acceleration according to Newton's 2nd Law?

Back

According to Newton's 2nd Law, as mass increases, acceleration decreases for a given force. This means more force is needed to accelerate a heavier object.

Front

What is the law of action and reaction?

Back

Newton's 3rd Law states that for every action, there is an equal and opposite reaction. This means that forces always occur in pairs.

How does air resistance affect falling objects?

Back

Air resistance opposes the motion of falling objects, and when it equals the force of gravity, the object reaches terminal velocity.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be caused by a change in speed or direction.
