Newtons 2nd Law

Front

What does Newton's 2nd Law state about the relationship between force, mass, and acceleration?

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. This can be expressed with the formula: F = ma, where F is force, m is mass, and a is acceleration.

How does mass affect acceleration according to Newton's 2nd Law?

Back

According to Newton's 2nd Law, as the mass of an object increases, the acceleration decreases if the same force is applied. This means that heavier objects require more force to achieve the same acceleration as lighter objects.

If a force of 20 N is applied to a 2 kg object, what is its acceleration?

Back

The acceleration can be calculated using the formula a = F/m. Here, a = 20 N / 2 kg = 10 m/s².

Which object will accelerate more when the same force is applied: a tennis ball, a soccer ball, or a bowling ball?

Back

The tennis ball will accelerate the most because it has the least mass, and according to Newton's 2nd Law, less mass results in greater acceleration when the same force is applied.

What is the formula used to calculate acceleration in Newton's 2nd Law?

Back

The formula used to calculate acceleration is a = F/m, where a is acceleration, F is the net force applied, and m is the mass of the object.

If a 5 kg object is pushed with a force of 12 N, what is its acceleration?

Back

Using the formula a = F/m, the acceleration is a = 12 N / 5 kg = 2.4 m/s².

What is the unit of force in the International System of Units (SI)?

Back

The unit of force in the SI system is the Newton (N).

Front

What happens to the acceleration of an object if the net force acting on it is doubled while its mass remains constant?

Back

If the net force is doubled while the mass remains constant, the acceleration will also double, according to Newton's 2nd Law.

What is the relationship between net force and acceleration?

Back

The relationship is that the net force acting on an object is directly proportional to the acceleration of that object, meaning that greater force results in greater acceleration.

How can you increase the acceleration of an object without changing the force applied?

Back

To increase the acceleration of an object without changing the force, you can decrease the mass of the object.
