Answer and see the solution →A cyclist is riding along a straight, level road. The diagram shows the horizontal forces acting on the cyclist and bicycle:
Diagram showing two forces acting horizontally on a bicycle (left: forward force from cyclist, right: friction from road) (a)[2 marks]Calculate the resultant force acting on the cyclist and bicycle.
(b)[2 marks]State what happens to the motion of the cyclist as a result of this resultant force.

Answer and see the solution →Explain why friction is sometimes useful and sometimes a problem in everyday life. Refer to one example of each.
Question 4
2 marks · Normal
Answer and see the solution →State two effects a force can have on an object.
Question 5
4 marks · Normal
Answer and see the solution →A satellite in space is affected by two main forces: the gravitational force of attraction from the Earth, and a small force from the solar wind acting in the opposite direction.
(a)[1 mark]Name the type of force that pulls the satellite towards the Earth.
(b)[2 marks]Explain the nature of gravitational force.
(c)[1 mark]If the force from the solar wind is 0.5 N and the force due to gravity is 100 N, calculate the resultant force on the satellite (assume both act along the same line but in opposite directions).

Answer and see the solution →A person combs their hair and notices that some hairs are attracted to the comb. Explain why this happens and name the type of force involved.
Question 7
2 marks · Normal
Answer and see the solution →An ice skater glides across an ice rink and gradually slows down until stopping. Use scientific reasoning to explain why the skater eventually stops, and what type of force is involved.

Question 9
4 marks · Normal
Answer and see the solution →A football is resting on a field. A player kicks the football, making it move, and it eventually comes to a stop.
(a)[2 marks]State two different effects that a force can have on an object. For each effect, give an example involving the football.
(b)[2 marks]Explain which force causes the football to slow down and eventually stop after being kicked.
