Newtons law

Newton`s first law

• F=ma

• Fnet=0,V=const

• F₁=-F₂

• none

Newton`s second law

• F=ma

• Fnet=0

• F1=F2

• none

Inertia is a property of matter

• False

• True

• none

• I don`t know

Mass of an object = 5 kg, net force F = 20 N. Determine the acceleration

• 100 m/s²

• 0.25 m/s²

• 4 m/s²

• 5m/s²

Object’s mass = 2 kg, F1 = 5 N left side, F2 = 3 N right side. Determine the magnitude and direction of the acceleration?

• 1 m/s² right side

• 1 m/s² left side

• 4 m/s² right side

• 4 m/s² left side

Object’s mass = 2 kg, F1 = 10 Newton, F2 = 1 Newton. The magnitude and direction of the acceleration is…

• a = 2 m/s² right

• a = 2 m/s² left

• a = 5 m/s² right

• a = 5 m/s² left

What is the Friction Force ?

• moving by gravity

• on a surface of object

• Force is the opposite of motion

• force acts spring to strech or compress

F₁ = 10 Newton, F₂ = 1 Newton, m₁ = 1 kg, m₂ = 2 kg. Find the acceleration ?

• 11 m/s²

• 0,3 m/s²

• 3 m/s²

• 4,5 m/s²

The acceleration of object depends upon both force as well as mass

• True

• False

• I don`t know

• impossible

• May be easy to move

• I don`t know

• Because of its large size

• Because they are afraid
