Three Newton´s Law

What describes the first law of newton?

• describes what occurs when there is no net force action on an object.

• relates accelerated motion to a net applied force.

• describes the sy,mmetrical relationship between two interacting bodies.

The force we exert makes things _____.

• fly

• disapear

• move

• progress

Can force occur without a force?

• true

• false

Can you have forces acting on an object without it having motion?

• ture

• false

what is the difference between the motion of a person that slid on ice versus or a person who slid on a waxed tile flood?

• the weight

• the momentum

• the force

• the frictional force

What would happen if the frictional force were to disapear?

• an object would move a constant speed along a straight line forever.

• the object would move in relation to their mass

• the object will be expected to move longer

• the object will not move

when a net force acting on an object is zero, the object´s momentum does not change.

• first newton´s law

• second newton´s law

• third newton´s law

Any change in the momentum arises from a change in ______.

• aceleration

• velocity

• speed

• momentum

Galileo introduced the term of ____________

• intertia

• speed

• moving

• spethors

What is intertia?

• the tendency of an object to keep moving in a straight line at a constant speed

• to remain stationary when zero net force acts on it.

• to increase the velocity due to gravity force

• to calculate the forces that act on an object.
