Answer and see the solution →An astronaut drops a tool with a mass of 2.5 kg on a planet where the gravitational field strength is 4 N/kg. Calculate the weight of the tool.
Question 4
3 marks · Easy
Answer and see the solution →Explain why a falling coin eventually stops accelerating and continues to fall at a constant speed. Include what happens to the forces acting on it.
Question 5
2 marks · Easy
Answer and see the solution →Calculate the weight of a backpack with a mass of 3.0 kg on Earth. Use g = 10 N/kg.
Question 6
3 marks · Easy
Answer and see the solution →A tennis ball is dropped from a balcony. It falls straight down through the air.
(a)[1 mark]State the two forces acting on the tennis ball as it falls.
(b)[1 mark]As the ball falls faster, describe what happens to the size of the air resistance.
(c)[1 mark]Eventually the ball falls at a constant speed. What is the name of this constant speed?
Question 7
3 marks · Easy
Answer and see the solution →A cyclist is moving quickly down a hill and eventually reaches a speed where her speed does not increase any further, even though she is still going downhill.
Explain why the cyclist does not keep speeding up. In your answer, refer to the forces acting on the cyclist.
