Forces

Front

What is the formula for calculating force?

Back

F = ma (Force = mass × acceleration)

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What does Newton's 1st law of motion state?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is the unit of force in the International System of Units (SI)?

Back

Newton (N)

Front

What is friction?

Back

Friction is the force that opposes the relative motion of two surfaces in contact.

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two masses.

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object, calculated as W = mg (Weight = mass × gravitational acceleration).

Front

What is the acceleration of an object if a net force of 10 N is applied to a mass of 2 kg?

Back

5 m/s² (using F = ma, acceleration = 10 N / 2 kg).

Front

What does Newton's 2nd law of motion state?

Back

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

Front

What is the effect of balanced forces on an object?

Back

Balanced forces do not change the object's motion; it remains at rest or continues moving at a constant velocity.
