Force Concept Inventory

All the statements about force are correct, except…

• Force occurs if push or pull process are acting on

  object a result of its interaction with another object.

• Force is a physics quantity that has magnitude

  without direction.

• The unit of force is kg.m/s 2 or Newton

• Force is depended on mass and acceleration of the

  object where the force acted.

Which one is not the effects of force on object…

• Changes direction of object

• Changes acceleration of object

• Changes position of object

• Changes amount of substance of object

These are the list of contact force, except…

• Normal force

• Friction

• Magnetic force

• Tension force

A ball rolling on the ground slows down and

finally stops because

• force of trust

• less force applied

• Friction

• gravitation force

A boy applies a pushing force on a ball thrown into the

air. What kind of applied force that pulling on the ball

down at the same time?

• The height of the boy

• Friction Force

• The mass of the ball

Which the following is incorrect statement about mass

and weight…

• Mass is amount of matter in a body. The weight is

  gravitational force acting on object.

• Mass will not change but weight can change

  because it depends on gravitational acceleration in

  the area

• Mass is measured by using spring balance and

  weight is measured by using triple balance

• SI unit of mass is kg and SI unit for weight is

  Newton

An object has a mass of 2.5 kg. When gravitational

acceleration is 10 m/s 2 then the weight of that object

is…

• 0,4 N

• 25 N

• 40 N

• 250 N

In laboratory on earth, balances show that an object

has a mass 15 kg with g = 10 m/s 2 . The same

balances and object are taken to another planet Z

where the gravitational acceleration on this planet is

three times bigger than the earth’s.

What is the mass and weight on this planet Z ?

• m = 15 kg, W = 150 N

• m = 15 kg, W = 450 N

• m = 150 kg, W = 1500 N

• m = 450 kg, W = 150 N
