SMS Newton's 3 Laws of Motion (2024-2025)

What are Newton's 3 Laws of Motion?

Back

1. First Law: An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force. 2. Second Law: The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma). 3. Third Law: For every action, there is an equal and opposite reaction.

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the mass of the object.

Front

What does it mean for an object to be in free fall?

Back

An object is in free fall when the only force acting on it is gravity, causing it to accelerate downwards.

Front

How do you calculate force using mass and acceleration?

Back

Force (F) is calculated using the formula F = m * a, where m is mass and a is acceleration.

Front

What happens to the motion of an object when balanced forces act on it?

Back

When balanced forces act on an object, it remains at rest or continues to move at a constant velocity.

Front

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

Back

The relationship is described by Newton's Second Law: the acceleration of an object is produced by a net force acting on the object and is inversely proportional to its mass.

Front

What is the effect of unbalanced forces on an object?

Back

Unbalanced forces cause an object to accelerate in the direction of the net force.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) is calculated using the formula a = (final velocity - initial velocity) / time.

Front

What is the significance of the direction of force in motion?

Back

The direction of force determines the direction of acceleration and thus the motion of the object.

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two masses, which causes objects to fall towards the Earth.
