Name some forces and know when they will act on an object
Friction force when an object moves along a surface. Gravity force the downwards pull of lager objects. Air resistance force is a type of friction force but happens when moving through air.
2 of 7
Describe the effect of balanced or unbalanced forces on the motion of an object
Balanced=no movement or no change in speed. Unbalanced= movement and increase of speed.
3 of 7
Calculate a resultant force
50→ - 30← = 20→
4 of 7
Describe how friction may change in different surfaces
The rougher it is the more friction there will be.
5 of 7
Calculate speed, distance or time using the D = S x T equation
S ÷ T = D D ÷ S = T
6 of 7
Describe the difference between mass and weight
Mass is the amount of matter it contains. Weight is how much gravitational force is between it and the earth.
