1) Define resultant force.
2) Work out the resultant force acting on the ball below.
2) Work out the resultant force acting on the ball below.
3) Work out the resultant force acting on the ball below.
4) A ball has two forces acting on it; one force is acting towards the right and the other force is acting towards the left.
The resultant force acting on the ball is 6 N towards the left. Work out the size of the force acting towards the left.
5)
a)
i) If the resultant force acting on a stationary object is 0, what will happen to the object?
ii) If the resultant force acting on a moving object is 0, what will happen to the object?
b) If the resultant force acting on an object is non-zero, what are the 5 different things that can happen to the object?
6) The cyclist below is travelling towards the right.

6) The cyclist below is travelling towards the right.
The cyclist provides a driving force of 350 N. The resistive forces (air resistance and friction) are 200 N.
a) Add the driving force and the resistive forces to the sketch of a bike. Do not worry about the lengths of the arrows.
b) Work out the resultant force.
c) What will happen to the motion/ velocity of the cyclist? Explain your answer.
7) The car below is travelling towards the right. The two resistive forces (air resistance and friction) are shown on the diagram below.
a) Add the driving force and the resistive forces to the sketch of a bike. Do not worry about the lengths of the arrows.
b) Work out the resultant force.
c) What will happen to the motion/ velocity of the cyclist? Explain your answer.
7) The car below is travelling towards the right. The two resistive forces (air resistance and friction) are shown on the diagram below.
a) The driving force is 1,900 N. Add this to the diagram. Do not worry about the lengths of the arrows.
b) What is the resultant force acting on the car?
c) What will happen to the motion/ velocity of the car? Explain your answer.
8) The diagram below shows a book sitting on top of a table.
b) What is the resultant force acting on the car?
c) What will happen to the motion/ velocity of the car? Explain your answer.
8) The diagram below shows a book sitting on top of a table.
The book is stationary (it stays on the table in the same position).
a) What is the resultant force acting on the book?
b) Draw and label the two forces acting on the book.
9) There are many forces acting on the ball below. The forces are acting up, down, left and right.
a) What is the resultant force acting on the book?
b) Draw and label the two forces acting on the book.
9) There are many forces acting on the ball below. The forces are acting up, down, left and right.
Find the resultant force acting on the ball.
