F=ma

Front

What does F=ma represent in physics?

Back

F=ma is Newton's second law of motion, which states that the force (F) acting on an object is equal to the mass (m) of the object multiplied by its acceleration (a).

Front

How do you calculate mass using force and acceleration?

Back

Mass can be calculated using the formula m = F/a, where F is the force applied and a is the acceleration.

Front

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

If a 10 kg object accelerates at 15 m/s², what is the force applied?

Back

The force can be calculated using F = ma, so F = 10 kg * 15 m/s² = 150 N.

Front

What is the formula to calculate acceleration?

Back

Acceleration can be calculated using the formula a = F/m, where F is the force applied and m is the mass of the object.

Front

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

Back

The relationship is described by Newton's second law, which states that force is the product of mass and acceleration (F = ma).

Front

What is the acceleration of an object if a force of 50 N is applied to a mass of 500 g?

Back

First, convert 500 g to kg (0.5 kg). Then use a = F/m, so a = 50 N / 0.5 kg = 100 m/s².

Front

What is the acceleration of a basketball with a mass of 0.60 kg when a force of 10.8 N is applied?

Back

Using a = F/m, a = 10.8 N / 0.60 kg = 18 m/s².

Front

What is the significance of the unit 'm/s²'?

Back

The unit 'm/s²' represents acceleration, indicating how much the velocity of an object changes per second.

Front

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

Back

If the mass increases and the force remains constant, the acceleration will decrease, as acceleration is inversely proportional to mass (a = F/m).
