friction 2

Friction is a

• Contact force

• Non contact force

• Gravitational force

• Normal force

Opposes relative motion between two objects is called

• Force

• Acceleration

• Friction

• Pressure

Formula for weight is

• W=Mg

• F=ma

• P=F/a

• W=Ma

Normal force and weight of object acting on a book placed on a table is

• Opposite to each other

• Same direction

• Along the x axis

• We can't say

Unit for friction is

• Metre per second

Force and frictional force acting on a object is

• Same direction

• Opposite direction

• Along y axis

• Zero

Frictional force is a

• Vector quantity

• Scalar quantity

• Both vector and scalar

• None

Net force acting on y axis

• 1

• Zero

• Infinity

• We can't say

Frictional force having

• Both magnitude and direction

• Only magnitude

• Only direction

• No direction and no magnitude

A physical quantity which has only magnitude no direction

• scalar
