The first law of motion has another name which is ----------------------, it states that an object at rest will remain at rest unless a force acts on it and move it.

• Gravitational force

• Inertia

• Acceleration

• Weightlessness

First law of motion " or Ineria " also states that an object which is already moving will keep moving in the same direction and speed unless ______________.

• it losses weight

• A force acts on it

• it losses mass

• Gravity disappears

Acceleration is the change in -----------------------------. ( Two answers for this question"

• Position

• Velocity

• Speed or direction

• Time

Velocity is a vector because it is made of ___________and _________

• Time and speed

• Magnitude (speed) and direction

• Nothing

• Distance and time

Second law of motion states that the acceleration of an object depends on the __________of the object and the ________acting on it.

• color, force

• size , force

• force, smell

• mass , force

You are in a supermarket, and you have two trollies, one is empty and the other is full, which one will accelerates mores if same force was applied to both trollies ?

• The empty one

• The one that is full of itmes

In the question of the two trollies in the supermarket, the empty trolley will move with higher acceleration because it has __________

• More mass

• Less mass

• no mass

If you drop a feather and a ball from the top of a building, the two will arrive at same time only in case there was no __________________

• gravity

• mass

• air resistance

• pressure
