Investigating force and energy
1.Force
2.Movement
1.1 Definition
Pull an action of
Effect
friction
bringing an object towards us
Push an action of moving an object away
Move a stationary object Stop a moving object Change direction of moving objects Make objects move faster or slowly Change the shape of an object
Friction
Definition a force that oppose motion
Effect produce heat difficult to move wear and tear
Advantages 1. holding thing 2. walk without slipping 3. car brake work properly
Disadvantages 1. worn out the surface 2. machine works slower / damage
Reducing
Increasing
lubricant oil, wax, grease or water Rough surface Ball bearing rollers Air cushion Smooth contact surface Talcum powder Dry surface
2.1.1 State that an object which moves faster travels a longer distance in a given time
2. Movement 2.1 Understanding speed
2.2.1 State that an object which move faster take a shorter time to travel a given distance
2.1.3 State what speed is 2.1.4 solve problems using formula A measurement on how fast an object moves
Speed = distance / time
Unit - km/h, m/s , cm/s
