Newton's three laws of motion

What is Newton's first law of motion?

• An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force

• A force is a push or a pull that acts upon an object

• The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

• For every action, there is an equal and opposite reaction.

What is an example of Newton's first law?

• When you hit a curb while on a skateboard and fly forward.

• When you snore in your sleep.

• When you sit still in a chair

• When you play Minecraft.

What is inertia?

• A push or pull

• A balanced force

• the resistance an object has to a change in its state of motion.

• An unbalanced force

Who developed the concept of inertia

• Isaac Newton

• Galileo Galilei

• Albert Einstein

• Tom cruise

Why do you have to wear a seatbelt?

• Its looks good

• To prevent you from moving forward when you stop suddenly.

• You don't wear a seatbelt.

• Seatbelts are only for little kids.
