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 an unbalanced force?

Back

An unbalanced force is a force that causes an object to accelerate, as it results in a net force acting on the object.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

How do you calculate force using mass and acceleration?

Back

Force (F) is calculated by multiplying mass (m) by acceleration (a): F = m × a.

Front

What is the mass of an object if a force of 132 N is applied to accelerate it at 2 m/s²?

Back

The mass of the object is 66 kg.

Front

What is the unit of mass?

Back

The unit of mass is the kilogram (kg).

Front

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

Back

The force applied is 150 Newtons.

Front

How do you calculate acceleration?

Back

Acceleration (a) is calculated by dividing the net force (F) by the mass (m): a = F / m.

Front

What is the acceleration of a 5 kg block pulled by a net force of 32 N?

Back

The acceleration is 6.4 m/s² (calculated as 32 N ÷ 5 kg).

Front

What happens to an object when unbalanced forces act on it?

Back

The object will accelerate in the direction of the net force.
