F=ma

Front

What does F=ma stand for?

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

What is the SI unit of force?

Back

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

Front

How do you calculate acceleration using force and mass?

Back

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

Front

If a force of 50 N is applied to a 500 g object, what is its acceleration?

Back

100 m/s².

Front

What is the relationship between mass and acceleration in F=ma?

Back

As mass increases, for a constant force, acceleration decreases.

Front

What is the formula to calculate force?

Back

Force (F) can be calculated using the formula F = m × a, where m is mass and a is acceleration.

Front

What is the mass of an object if a force of 20 N produces an acceleration of 4 m/s²?

Back

The mass is 5 kg (m = F/a = 20 N / 4 m/s²).

Front

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

Back

The acceleration is halved.

Front

What is the force required to accelerate a 1000 kg car at 3 m/s²?

Back

The force required is 3000 N (F = m × a = 1000 kg × 3 m/s²).

Front

If a 5 kg block is pulled with a net force of 32 N, what is its acceleration?

Back

The acceleration is 6.4 m/s² (a = F/m = 32 N / 5 kg).
