G4 5.1 & 5.2 Gravity, normal force and applied force & satellite

Why don't the people staying in the south pole of earth fall off?

• Due to applied force

• Due to contact force

• Due to normal force

• Due to gravity

Gravity pulls everything

• upwards

• downwards

Gravity works on

• moving objects

• objects at rest

• both objects at rest and moving objects

A force acting on an object that is in contact with another object

• Gravitational force

• Normal force

• Applied force

In a force diagram, forces are represented by

• Lines

• dots

• Arrows

The red arrow this picture represents

• gravitational force

• normal force

• applied force

• none of the above

Arrows of the same size means

• they are equal forces

• they are not equal forces

Any force that is applied to another object or person is called

• a contact force

• An applied force

• gravitational force

In this force diagram, A is ...................... and B is .................................

• Normal force , gravity

• Gravity , Normal force

The applied forces in the given images in order are

• Push and pull

• pull and push
