Heat Numericals: Explanation, Formulae and Practice
Physics questions become easier when you write the known values, choose the right relation, convert units and then substitute carefully.
Useful Formulae
- Speed = distance / time.
- Force = mass x acceleration.
- Work = force x displacement in the direction of force.
- Power = work / time.
- Ohm law: V = I x R.
Solved Example
Question: A body covers 120 m in 20 s. Find its speed.
Working: Speed = distance / time = 120 / 20.
Result: Speed = 6 m/s.
Unanswered Practice Questions
Try these yourself before checking notes or calculators.
- Find force when mass is 10 kg and acceleration is 2 m/s^2.
- Find work done when a 5 N force moves an object by 4 m.
- Using V = IR, find voltage when current is 2 A and resistance is 6 ohm.
