These questions and answers have been created with the specification as an aid, so bear that in mind when reading up on the explanations afterwards. When finished, it will take all of Physics Unit 2 into account.
Whenever two objects interact, the forces they exert on each other are equal and opposite.
Respuesta
True
False
Pregunta 2
Pregunta
What is a resultant force?
Respuesta
A number of forces acting at a point may be replaced by a single force that has the same effect on the motion as the original forces all acting together. This single force is called the resultant force.

The resultant force is the force that acts on objects and as a direct result of this, the objects will remain stationary.
Pregunta 3
Pregunta
If the resultant force acting on a stationary object is zero, what will happen to the object?
Respuesta
It will remain stationary.
It will accelerate.
It will decelerate.
Pregunta 4
Pregunta
If the resultant force acting on a moving object is not zero, what will happen to the object?
Respuesta
It will always become stationary.
It will always accelerate.
It will always decelerate.
It speeds up, slows down or changes direction depending on the direction and power of the resultant force.
