Newton's Second Law 2019

Front

What is Newton's Second Law of Motion?

Back

The greater the mass of an object, the greater the force needed to change its motion.

Front

How is force calculated according to Newton's Second Law?

Back

Force (F) is calculated as the product of mass (m) and acceleration (a): F = m * a.

Front

If an object has a mass of 4 kg and is subjected to a force of 20 N, what is its acceleration?

Back

The acceleration is 5 m/s².

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 the relationship between mass, force, and acceleration?

Back

Mass is directly proportional to force and inversely proportional to acceleration.

Front

What happens to the acceleration of an object if the net force acting on it is zero?

Back

The acceleration of the object is zero, meaning it maintains a constant velocity.

Front

What is the acceleration of an object traveling at a constant velocity?

Back

The acceleration is 0 m/s².

Front

If a car with a mass of 2000 kg accelerates at 20 m/s², what is the net force applied to it?

Back

The net force is 40,000 N.

Front

What factors affect the acceleration of an object?

Back

The mass of the object and the net force acting on it.

Front

What does acceleration change in an object?

Back

Acceleration changes an object's speed, direction, or both.
