What would happen to an astronaut walking in space if there was no gravity affect on him?
Float away quickly
What example can you give for Inertia of Motion? In a car that suddenly stops or turning a corner

As you are in a car sriving and you go around a corner, the car goes one way and you go the opposite way. What type of inertia is this? Inertia of motion or inertia of direction
Inertia of direction
Why do you think that gravity on the moon is less than on earth? Is it to do with the atmosphere or with the weight of the moon?
Weight of the moon
Why do you weigh less on the moon? Due to less gravitational pull or due to the composition of the moon?
Less gravitational pull
Is gravity a force that attracts or repels?
Attracts
