What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is the formula for calculating force?

Back

Force (F) is calculated using the formula F = mass (m) × acceleration (a).

Front

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

Back

The unit of force is the Newton (N).

Front

What is deceleration?

Back

Deceleration is the rate at which an object slows down, often expressed in meters per second squared (m/s²).

Front

How does mass differ from weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What is the effect of air resistance on falling objects?

Back

Air resistance opposes the motion of falling objects, affecting their acceleration and the time it takes to reach the ground.

Front

What happens to the mass of an object when it is taken to the Moon?

Back

The mass of an object remains the same regardless of its location, whether on Earth or the Moon.

Front

What is the relationship between mass and weight?

Back

Weight is the product of mass and gravitational acceleration (W = m × g), where g is approximately 9.81 m/s² on Earth.

Front

What is the significance of an unbalanced force?

Back

An unbalanced force causes an object to change its state of motion, either by accelerating, decelerating, or changing direction.

Front

What is the principle of conservation of momentum?

Back

The total momentum of a closed system remains constant if no external forces act on it.
