Calculating Force

Front

What is force?

Back

Force is a push or pull on an object that can cause it to accelerate, change direction, or change shape.

Front

What is the formula to calculate force?

Back

Force (F) = Mass (m) × Acceleration (a)

Front

If an object has a mass of 10 kg and is accelerated at 2 m/s², what is the force?

Back

20 Newtons

Front

How much force is needed to accelerate a 1,800 kg truck at 3 m/s²?

Back

5,400 Newtons

Front

What is mass?

Back

Mass is the amount of matter in an object, usually measured in kilograms (kg).

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity, measured in meters per second squared (m/s²).

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to accelerate, resulting in a change in motion.

Front

What happens when forces are balanced?

Back

When forces are balanced, the object remains at rest or continues to move at a constant speed in a straight line.

Front

In a tug of war, if one team pulls with a force of 45 N and the other with 50 N, what is the net force?

Back

5 N to the right.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).
