1.1. Two students are discussing mass and weight.

Student 1 claims that a person's weight will be different on Mars than it is on Earth. 

Describe the difference between mass and weight, and explain whether you agree with Student 1.

1.2. Identify the vector quantities.

Tick all the boxes that apply. 

$□$ displacement

$□$ distance

$□$ speed

$□$ velocity

1.3. Two forces act at right angles to one another: a 35 N force acts to the right and a 42 N force acts downward.

Construct a scale diagram showing the effect of these two forces, and label the resultant force as X.

Use the scale 10 N = 1 cm

1.4. Calculate the magnitude and direction of the resultant force of the forces acting from part (c) 

magnitude of resultant force = ....................................

direction of resultant force = .......................to the horizontal
