SCIENCE FORM 2 CHAPTER 8

Force is a ______________ or a ________________ .

• energy , pull

• push , pull

• movement , static

• kinetic energy , potential energy

List the types of forces

• Buoyant force, Elastic force, Frictional force, Weight, Normal force and Gravitational force

• Buoyant force, Elastic force, Frictional force, mass, Normal force and Gravitational force

• Floating, Elastic force, Frictional force, Weight, Normal force and Gravitational force

Force is a vector quantity that has _____________________ and

direction ________________.

• magnitude , pull

• magnitude , direction

• pull , magnitude

• energy, line

Newton’s Third Law states that for every

action force, there is a _____________________ of

the same magnitude but in the opposite

direction.

• upthrust force

• down force

• reaction force

• motion force

Every object when it is placed on a surface the object is acted by a reaction force to support the weight from the surface called ________________________

• reaction force

• pull force

• normal force

• weight force

Diagram shows a football being kicked by a player.

Name the forces involved in this situation.

• impulsive force

• electric force

• buoyant force

An object will float if the buoyant force acting on

it is enough to support its ______________,that is

the buoyant force = ____________________________

• frictional force , weight

• normal force , weight

• weight, weight

Conversely, an object will submerge if the

buoyant force acting on it is not enough to

support its ___________________.

• force

• weight

• surface

When an object that is less dense than a liquid

is pushed into the liquid, the buoyant force

(upthrust force, F) is ______________ than weight (W).

• less

• more

• equal

When an object is more dense than

the liquid, the buoyant force (upthrust force, F)

is ______________ than the weight (W) of the object.

• less

• more

• equal
