This test focuses on everyday science MCQs on motion, energy and work. These ideas help us understand how things move, how energy is used and how work is done in our daily lives. By solving these questions, you will see how science works all around you.
This test is made simple and fun, just for young learners like you. The everyday science MCQs will not only help you with school exams but also make you think about the world in a whole new way. You’ll learn how to connect what you study in class to real-life examples, like playing sports, riding a bike or even using a flashlight.
Everyday Science MCQs: Motion, Energy an Work
Which of the following is the true definition of motion?
- A thing that makes something move faster.
- A change in the position of an object compared to others.
- Something that always stays in one place.
- A force that stops something.
Right Answer: (B) A change in the position of an object compared to others
What is the main thing you must overcome to move an object?
- Gravity
- Inertia
- Friction
- Speed
Right Answer: (B) Inertia
Which of the following is the true definition of friction?
- A force that helps things move.
- A force that stops things from sliding or rolling easily.
- A push that makes things fly.
- A power that pulls things down.
Right Answer: (B) A force that stops things from sliding or rolling easily
Why does oil or grease are used in a machine?
- It makes the machine slower.
- It reduces friction so parts move smoothly.
- It increases the weight of the machine.
- It stops the machine completely.
Right Answer: (B) It reduces friction so parts move smoothly
How can we calculate momentum?
- Mass is multiplied by speed.
- Weight divided by time.
- Speed minus friction.
- Force divided by distance.
Right Answer: (A) Mass multiplied by speed
Why do we need more effort to stop a heavy wheel?
- Because it has more friction.
- Because it has more inertia.
- Because it spins too fast.
- Because it is small.
Right Answer: (B) Because it has more inertia
What happens if two objects bump into each other and one is lighter?
- The lighter object moves backward.
- Both stop moving.
- The heavier object falls over.
- Both objects stay still.
Right Answer: (A) The lighter object moves backward
Why do we use wheels and ball bearings in machines?
- They make the machine heavier.
- They stop the machine.
- They reduce friction and make moving easier.
- They increase the size of the machine.
Right Answer: (C) They reduce friction and make moving easier
Why do skaters move so easily on ice?
- Because ice reduces friction.
- Because they push the ice with their feet.
- Because gravity is less on ice.
- Because ice makes them lighter.
Right Answer: (A) Because ice reduces friction
What is speed?
- How fast something is moving.
- How heavy an object is.
- The size of an object.
- The power to lift an object.
