Who knows there may be the next Einstein hidden inside you? We believe in you, we believe in your capabilities, now let us help you to reach your full potential and make you the next Science genius.
Join our innovative classes of secondary science tuition, primary science tuition, ip science tuition in Singapore today and notice change in your grades within just a few days.
Pushing and Pulling are two very common actions that we do every day, and when this 2 action are applied on something else, it is a force. In today’s primary science tuition lesson with Miracle Learning Centre, we will be discussing about how force brings about movement of objects.
“So what exactly is a force? Where can we see force being applied?” a student from Miracle Learning Centre class asked.
” Well, force actually can’t be seen, they are usually felt through the force exerting on us due to the effects. There are many examples of applied force, just like how you on and off the light switch at home, the pushing of the switch itself is a pushing action and that is a force!”
Your science tuition teacher will tell you what are the different effects of a force? A force has 4 different effects so let’s go through them one by one. The first effect of force is that a force can make an object move as well as change the speed of the object to be faster or slower. When you exert force on the object, it is able to move. The greater force you apply on the object, the faster and further it moves depending on the amount of force we apply on it.
The second effect of force is that a force can make a moving object change direction either forwards, backwards or to the side. Imagine yourself playing badminton with your friends, when your friend hits the shuttle cock to you, it flies to you in your direction. However, when you hit the shuttle cock using your racquet in retaliation, it will be able to fly back to your friend in an opposite direction? This is because a force when applied, is able to change the direction of the moving object.
The third effect of force is that a force can slow down and stop a moving object just like how cyclists are able to stop the bike by putting their leg down on the ground. The mechanism serves as a force that allows the bike to slow down and stop.
Last but not least, have you ever played with plasticine or dough during art class? Did you notice how the shape of the dough is able to change with just a little stretch by your hands? This is because a push or pull by your hands is actually exerting force on the dough, allowing the shape of it to be changed. Force can also change the shape of an object!
Now, after explaining the different effects of forces, we have come to the end of our primary science tuition lesson at Miracle Learning Centre where we provide fun activities and worksheets for all primary science tuition students. We hope you have learnt something new today and we’ll see you at our next Science tuition lesson!
