- Newton's First LAW of Motion
- My body should've kept moving ahead according to Newton's first LAW! I was able to stay in the car thanks to my seatbelt!
- Oh gosh, my car was involved in a collision! Why did my body not hit with my dashboard?
- Newton's first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.
- My seatbelt held me in place and kept me from moving forward. It stopped my body's inertia by acting as an imbalanced force. Newton's first law came to my rescue!
- This first law can also be applied to our everyday interactions with objects. For example, a book lying on the table remains at rest as long as no net force acts on it. In summary, a moving object does not stop moving by itself.
- Newton's Second Law of Motion
- The bigger box contains bricks, whilst the smaller box has merely paper. Maybe it has something to do with how quickly the boxes move when I push them.
- Hmm... I'm pushing these two boxes with equal effort, but the larger one is going slower than the smaller one!
- The speed and direction of the boxes are determined by the amount of force I use to push it and the mass of the box, according to Newton's Second Law! Because the smaller box simply contains paper, pushing it rather than the larger box is faster.
- Newton's Second Law States: that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object.
- Various forces have an impact on our day-to-day existence. The Earth, as you may know, exerts a pull on us known as gravity. Newton's Second Law states that a net force alters an object's velocity by altering its speed or direction.
