Force equals mass times acceleration

Front

What is the formula for calculating force?

Back

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

Front

What is mass?

Back

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

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, measured in meters per second squared (m/s²).

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

If a 50 kg skater accelerates at 5 m/s², what is the force applied?

Back

250 N (Force = 50 kg × 5 m/s²).

Front

What is Newton's 1st Law of Motion?

Back

An object in motion will stay in motion and an object at rest will stay at rest unless acted upon by an unbalanced force.

Front

What is the net force when two forces act in the same direction?

Back

The net force is the sum of the two forces.

Front

If a 12 N net force is applied to a 3 kg object, what is its acceleration?

Back

4 m/s² (Acceleration = Force / Mass = 12 N / 3 kg).

Front

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

Back

The acceleration decreases.

Front

What is the force on a 1000 kg elevator falling freely at 9.8 m/s²?

Back

9,800 N (Force = 1000 kg × 9.8 m/s²).
