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 unit of force in the SI system?

Back

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

Front

How do you calculate mass using F=ma?

Back

To calculate mass, rearrange the formula to m = F/a, where F is the force applied and a is the acceleration.

Front

If a force of 90 N is applied to a cart with a mass of 30 kg, what is the acceleration?

Back

The acceleration is 3 m/s² (calculated using a = F/m = 90 N / 30 kg).

Front

What is the relationship between mass and acceleration when a constant force is applied?

Back

As mass increases, acceleration decreases if the force remains constant.

Front

What is the acceleration of a 10 kg object when a force of 50 N is applied?

Back

The acceleration is 5 m/s² (calculated using a = F/m = 50 N / 10 kg).

Front

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

Back

The acceleration is halved.

Front

What is the formula to find acceleration?

Back

The formula to find acceleration is a = F/m.

Front

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

Back

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

Front

What is the mass of an object that accelerates at 4 m/s² when a force of 20 N is applied?

Back

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