Newton's Laws of Motion

​

Objective I will describe Newton’s Laws of Motion.

DOL Given 5 questions, I will describe Newton’s Laws of Motion in regards to force by explaining how everyday life activities prove Newton’s 3 Laws of Motion. Answering with 100% accuracy!.

​R.C.-Which law describes why the light ball goes farther when kicked with the same force?

Open Ended

Newton’s first law of motion states that objects will continue what they are doing, either staying still or moving, unless they are acted upon by a force. If a ball is sitting still on the grass, it will continue to sit still unless a force, such as a kick from a foot, causes it to move. Likewise, if an object is in motion, such as a rock rolling down a hill, it will continue its motion unless it is interrupted by a force such as a collision with a tree.

Annotate-What is the formula for Newtons second law?
When you push a toy car, it starts to move. The harder you push (force), the faster it goes! Scientists explain this using a formula: F = m x a, where:

• F is the force you apply,

• m is the mass of the car, and

• a is how quickly it speeds up (acceleration).

Imagine you have two cars, one small and one big. If you push both with the same force, the smaller car moves faster because it has less mass. This means that the bigger car needs more force to go as fast as the smaller one.

Multiple Choice

You have three objects:

• A toy car with a mass of 2 kg

• A scooter with a mass of 5 kg

• A heavy box with a mass of 10 kg

You push each object with the same amount of force. Think about how the mass of each object affects its speed.

If you want to make all three objects move at the same speed, what should you do to the force applied to each object?

• Apply less force to the toy car and more force to the heavy box.

• Apply less force to the heavy box and more force to the toy car.

• Apply the most force to the scooter and less to the toy car and the heavy box.

​

F=m X a

When you give a friend a lift on your bike, you have to pedal harder and faster to keep the same speed (acceleration) as you had when you were on your bike alone.

Have you ever tried to jump off a swing or push a friend on a skateboard? When you push on something, it pushes back on you! This is called Newton’s Third Law: For every action, there is an equal and opposite reaction.

Think about it like this: if you push on a wall, the wall pushes back on you with the same amount of force, even though it doesn’t move. Or, when you jump, your feet push down on the ground, and the ground pushes you up! That’s why you lift off.

In science, this means forces always work in pairs. Whatever you push will push back!
