Newton's Second Law Flashcard

Front

What is Newton's Second Law of Motion?

Back

Newton's Second 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 = ma, where F is the net force, m is the mass, and a is the acceleration.

What is the formula to calculate weight?

Back

Weight can be calculated using the formula: Weight (W) = mass (m) × acceleration due to gravity (g). On Earth, g is approximately 9.8 m/s².

If a car is moving at a constant velocity, what is the net force acting on it?

Back

The net force acting on a car moving at a constant velocity is 0 N, as there is no acceleration.

How do you calculate the mass of an object if you know the force applied and the acceleration?

Back

You can calculate the mass using the formula: m = F/a, where F is the force applied and a is the acceleration.

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

Back

If the mass of an object increases while the net force remains constant, the acceleration of the object will decrease.

What is inertia?

Back

Inertia is the property of an object to resist changes in its state of motion. The greater the mass of an object, the greater its inertia.

Front

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

Back

The relationship is defined by Newton's Second Law: F = ma. This means that force is the product of mass and acceleration.

If two objects of different masses are subjected to the same force, how will their accelerations compare?

Back

The object with the smaller mass will experience a greater acceleration than the object with the larger mass, given the same force.

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

Back

The net force can be found by summing all the individual forces acting on the object, taking into account their directions.
