What happens if ... You squeeze a spring then leave it free.
The spring will be pushed back when you leave it free
What happens if ... There is no gravity on Earth.
AII objects on its surface will float off into space
Give reasons for : Paper clips are pulled toward the magnet
Due to the force of magnetism
Give reasons for : The ball changes its direction after we throw it upwards.
Because gravity force always pull it downwards.
Give reasons for : Gravity of Earth Is greater than gravity of the moon.
Because the mass of Earth is greater than the mass of the moon
The force of attraction that changes the direction of a moving object in air towards the ground.
Gravity
The effect that pull or push an object to make it move.
Force
The change of an object position related to another object.
Motion
The force that is found between two magnets or between the magnet and an object.
Magnetism
The pulling force that causes object to fall down toward Earth's surface.
Gravity of Earth
true or false: Magnet must touch objects to attract them.
false
true or false: Force is the reason of motion of any body
true
true or false: The change of an object position is called force.
false
true or false: Magnet has an invisible force called magnetism.
true
true or false: The force of magnet is always attraction force only.
false
true or false: Gravity Is similar to magnetism because both of them has only pulling force.
false
