basic physics

State the effects of force on an object

• causes distortion of shape

• changes direction of moving

• changes object colour

• can affect the size of an object

1. Express each of the following to 3 s.f: 48938

• 489

• 48900

• 50000

• 4890

calculate the total distance covered

• 600 m

• 450 m

• 60 m

• 4500 m

find the initial velocity when a body comes to rest after 5 sec when decelerating at 10m/s²

• -50m/s

• 50m/s

• 2m/s

When we drop a coin and a feather simultaneously in a tube fill with air, which one will reach the bottom first?

• coin

• feather

• none of the above

• they will reach at the same time

A beaker is left out in the rains. Will the rate at which the beaker is filled be altered if wind starts to blow?

• yes

• no

• not sure

A coin was thrown vertically upwards and it rose to a length of 10 metres. What was the time taken by the body to reach the highest point?

• 1.43s

• 3s

• 2s

• 1.4s

which eclipse is shown on the diagram

• annular

• lunar

• solar

which property of sound is represented by the diagram

• refraction

• reflection

• travels in a straight line

• hits a barrier

this rule helps to determine

• direction of motion

• direction of current

• direction of magnetic field
