Physics Summer Exam

Front 1

What is force

Back 1

Anything that an object to change its velocity

Units Newton's (n)

Front 2

Force equation

Back 2

F=MxA

Force= mass x acceleration

Front 3

Momentum equation

Back 3

P= MxA

Momentum = mass x Acceleration

Front 4

Front 7

Newton's 3rd law

Back 7

Every action has an equal but opposite reaction

Front 8

Newton's 2nd law

Back 8

"if I kick u, u go with the force I kicked"Rate of change of an objects momentum Is proportional to the force that caused it

Front 9

Newton's 1st law

Back 9

"moves until force stops it" Object will remain at rest unless a force acts on it

Front 16

Inertia

Back 16

Resistance of an any object to a change in it velocity

"truck has brakes, its contents doesn't"

Front 17

Momentum

Back 17

P=mv = kgms

Calculated in kg

Front 20

Principle of conservation of momentum explain

Back 20

Momentum before =momentum after

Total momentum before collision =total momentum after collision

"shot fired from gun= gun recoils" (leaves barrel with a certain force

It's mass per unit volumes

Front 31

Kinetic energy equation

Back 31

2

Ek= 1/2 MV

Front 32

Law of floatation

Back 32

Weight of floating object is equal of the liquid it displaces

Duck weight =the water it splashed out

Front 33

Up trust

Back 33

Buoyancy force

If object is immersed in a liquid or gas, there is an unusual force acting on it. For is called up trust or buoyancy force

Front 34

Archimedes principle

Back 34

The up trust experienced by an object is equal to the weight of the fluid it displaces

Front 35

Boyles law

Back 35

When a gas is pumped into an enclosed space, it will shrink to that space

Front 36

Lever

Back 36

A rigid body which is free to rotate about a fixed point or fulcrum

Front 37

Moment equation

Back 37

M=F x D

Moment= Force x distance

(distance from fulcrum)
