Newton law. Link up

When we talk about the first Newton´s law, we tend to relate it to the following concept:

• Every body wishes the least amount of motion upon itself unless it is forced to change its state by forces impressed on it.

• if there is an external force, such force will be counteracted by an equal one, but in the opposite direction.

• Neither of the options

• law of inertia

A driver of a car crashes at high speed and, due to inertia, shoots forward. This is an example of

• First law of Newton

• Second law of Newton

• Third law of Newton

• Law of Gravitational movement

A woman pushes two children up a hill: a 4-year-old and a 10-year-old, so that they reach the same place with the same acceleration. With Newton´s second law in mind we can say:

• The woman will become more tired with the 10 year old, since their mass is bigger

• The 4 year old will need more strenght on himself to get to the same place with the same acceleration

• The woman is putting the same strenght in both kids, because they are travelling the same distance with the same acceleration

2 people on skates push each other, according to the tird Newton´s law they...

• Every skater will preserve itself unless it is forced to change its state by the other skater

• the product of the mass of one skater and its acceleration is directly proportional to the magnitude of the force acting on the second skater

• the force on one skater is equal and opposite to the force that interacts on the other one.

• No skater will move until there is a force provoking it to change

A magician approaches the table and pulls the tablecloth, surprisingly the glass plates and glasses do not fall, why does this happen?

• Because the plates and glasses were not acted upon directly, so they stay put

• because the magician did not move the plates slow enough

• because the magician expects the speed of the pulling to be enough not to disturb the plates

• Because the plates and glasses want to be as quiet as they were, and since they were not touched they didn´t fall

Take a look at the following image, because it is explaining the basis of:

• The first Newton´s law

• The second Newton´s law

• The law of dynamics

• The third Newton´s law

Another possible example of Newton's second law is a car that________ its march, thanks to the force that the engine imposes on it. The greater the _______ exerted by the work of the engine, the faster the car will go.

• Brakes/strength

• accelerates/ force

• stops/force

• accelerates/work

The moment you notice that pushing the grocery kart around when you are ready to go pay is harder than pushing it when it´s empty is the moment when you start to take into consideration Newton´s:

• First law

• Second law

• Third law

• None of the options

When a car is driven 100 km on a motorway for 65 km, it will undoubtedly use much less gasoline than if it had to drive at the same speed for the same distance in a truck. this is a representation of the law of innertia.

• True

• False

If we push a table while sitting in a wheelchair. The effect is that the chair moves away from the table. This statement to which law corresponds:

• Newton´s second law of movement

• Newton´s third law of movement

• Newton´s first law of movement

• Law of universal gravitation
