PS 2-1 | Newton's 2nd Law Calculation Check

Front

What is Newton's 2nd Law of Motion?

Back

Newton's 2nd Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. It can be expressed with the formula: F = m * a.

Front

How do you calculate force using mass and acceleration?

Back

Force (F) can be calculated using the formula: F = m * a, where 'm' is mass in kilograms and 'a' is acceleration in meters per second squared.

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

Back

The relationship is defined by Newton's 2nd Law: as mass increases, for a constant force, acceleration decreases.

How do you find the net force acting on an object?

Back

Net force can be found using the formula: F_net = m * a, where 'm' is the mass and 'a' is the acceleration.

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

Back

If the mass is doubled, the acceleration is halved, according to Newton's 2nd Law.
