The SI UNIT of the physical quantity FORCE is....(write the unit and the symbol)

When a force is exerted on an object, it can change the object’s: speed, direction of (a)   and the shape

When a force is applied to a spring, it stretches. The (a)   the force applied, the longer the spring stretches.

The symbol of the unit Newton is (a)  

When representing a force, you must draw an (a)   over the symbol of the force.

Whenever an object moves against another object, it feels (a)   force. This force acts in opposite direction to the movement. This force is much smaller on smooth surfaces that on rough surfaces.

Elastic materials and objects such as springs, change (a)   when a force is exerted on them.

A change in shape is called (a)  

Which of the following forces is always attractive? (a)  

Weight is measured in kg. (a)  

The weight of an object (a)  

(a)   is the force that keeps our feet on the ground

Two magnets (a)   each other when like-poles (two norths or two souths) are near each other.

The strongest magnets are made of (a)  

The force that equals 240 N is the girl's (a)  

When F1 and F2 are acting together, the net force (R) is: (a)  

Moving a box along a ramp (inclined plane) requires (a)   force than lifting it vertically.
