F=ma

Front

What does F=ma stand for?

Back

F=ma is Newton's second law of motion, where F is force, m is mass, and a is acceleration.

Front

How do you calculate force using mass and acceleration?

Back

Force (F) is calculated by multiplying mass (m) by acceleration (a): F = m × 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

If an object has a mass of 4 kg and accelerates at 3 m/s², what is the force applied?

Back

Force = 4 kg × 3 m/s² = 12 N.

Front

What happens to acceleration if the mass of an object increases while the force remains constant?

Back

If mass increases and force remains constant, acceleration decreases.

Front

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

Back

The relationship is direct; increasing force increases acceleration, while increasing mass decreases acceleration.

Front

If a 10 kg object accelerates at 5 m/s², what is the force applied?

Back

Force = 10 kg × 5 m/s² = 50 N.

Front

What is the mass of an object if a force of 20 N is applied and it accelerates at 4 m/s²?

Back

Mass = Force ÷ Acceleration = 20 N ÷ 4 m/s² = 5 kg.

Front

What is inertia?

Back

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

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia.
