Effects of Force on Motion

What can happen to an object's motion when a force is applied to it?

• The object's motion can speed up.

• The object's motion can disappear.

• The object's motion can become constant.

• The object's motion can become unpredictable.

Which of the following is a possible effect of applying force to an object?

• The object's motion can slow down.

• The object can become invisible.

• The object can change color.

• The object can become heavier.

When a force is applied, what can happen to the direction of an object's motion?

• The object's motion can change direction.

• The object's motion can become circular.

• The object's motion can become stationary.

• The object's motion can become erratic.

What is a load in the context of structures?

• The weight of an object itself

• The force exerted on the surface of an object

• The internal force within an object

• The speed of an object

What is an example of an external force acting on a structure?

• A person standing on a bridge

• A book on a shelf

• Snow on a roof

• All of the above

What is an example of an external force applied to a structure?

• Friction

• Gravity

• Internal tension

• Elasticity

What must an object be supported at to withstand external forces like gravity?

• Its base

• Its top

• Its center of gravity

• Its sides

What are the two types of external forces mentioned in the document?

• Dead load and Live load

• Static load and Dynamic load

• Permanent load and Temporary load

• Fixed load and Variable load

What is a dead load?

• A temporary force acting on the structure

• A permanent force acting on the structure

• A force that changes with time

• A force that acts only during construction

Which of the following is an example of a dead load?

• Wind pressure on a building

• Furniture inside a building

• The structure itself

• People moving inside a building
