Speed tells us how far an object moves in a given time.
The speed of an object does not depend on the direction in which it is travelling.
The velocity of an object is the speed and direction in which it is moving.
Acceleration= Change in Speed / Time for Change ------> m/s squared.
Every Force has an equal and opposite reaction.
The resultant force is the size of the unbalanced force.
If the forces acting on an object are unbalanced, then the object will accelerate.
Electric Charge is caused by having too few or two many electrons.
Static Electricity (or charge) is stationary electrical charge.
Moving Change is called current. You can only have static charge in insulators.
Two similar charges + and + or - and - will repel.
Two opposite charges…
