Newtons 2nd Law Practice

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 = ma.

Front

How do you manipulate the equation F = ma to solve for acceleration?

Back

To solve for acceleration, divide both sides of the equation by mass: a = F/m.

Front

What is the formula to calculate net force?

Back

The formula to calculate net force is F_net = ma, where F_net is the net force, m is the mass, and a is the acceleration.

If a car has a mass of 3,000 kg and is accelerated at 2 m/s², what is the net force required?

Back

The net force required is 6,000 N, calculated using F_net = ma (F_net = 3000 kg * 2 m/s²).

Front

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

Back

The relationship is that force is the product of mass and acceleration; increasing either mass or acceleration will increase the force.

If an object is accelerating at 3 m/s² and has a net force of 15 N, what is its mass?

Back

The mass of the object is 5 kg, calculated using m = F/a (m = 15 N / 3 m/s²).

What does it mean if an object has a net force of zero?

Back

If an object has a net force of zero, it is either at rest or moving at a constant velocity, indicating that all forces acting on it are balanced.

How can you determine the mass of an object using a graph of force vs. acceleration?

Back

You can determine the mass by finding the slope of the line in the graph, which represents the mass when using the formula F = ma.
