Resultant forces

Question 1

What happens what two objects interact

Answer 1

When two objects collide the forces the exert on each other are equal and opposite

Question 2

What is a resultant force?

Answer 2

A number of forces acting at a point causes a single force that has the same effect on the motion as the original forces acting together
E.g. If a object was stationary and object 2 with an equal weight collides with it, object 1 will move in the same velocity with the same momentum when there is no other factors such as friction acting on it. If object1 is double the weight of object 2 the momentum is halved

Question 3

What can happen when a resultant force is acting on an object?

Answer 3

It can change its state of rest or motion

Question 4

Two things that happens when a resultant force is stationary is…

Answer 4

Zero- the object remains stationary

Not zero l- the object will accelerate in the direction of the resultant force

Question 5

The two things that happen if the resultant force acting on a moving object is…

Answer 5

Zero- the object will continue to move at the same velocity

Not zero- the object will accelerate in the direction of the resultant force
