Physics Quiz

What are balanced forces?

• Forces that are unequal in strength and same in direction

• Forces that are equal in strength and opposite in direction

• Forces that cause an object to move in a circular path

• Forces that cause an object to accelerate

What is the result when balanced forces act on an object?

• The object moves in the direction of the larger force

• The object starts rotating

• The object remains at rest or continues to move at the same speed in the same direction

• The object accelerates in the direction of the applied force

What are unbalanced forces?

• Forces that are equal in size and cancel each other out

• Forces that are equal in size but opposite in direction

• Forces that are unequal in size or direction and that change an object's motion

• Forces that do not affect an object's motion at all

What is motion?

• The sound an object makes

• The color change of an object

• A change in the position of an object

• The smell of an object

What is potential energy?

• Energy that is being used to perform work

• Energy that is stored in an object

• The energy possessed by a body due to its motion

• The energy released during a chemical reaction

What is kinetic energy?

• The energy of position

• The energy of motion

• The energy stored in chemical bonds

• The energy released from a reaction

What does the formula s = d/t represent?

• Speed equals distance times time

• Speed equals distance divided by time

• Speed equals time divided by distance

• Speed equals the sum of distance and time

According to the speed triangle shown, what must you do to find the average speed?

• Multiply total distance by total time

• Divide total distance by total time

• Add total distance to total time

• Subtract total time from total distance

What is velocity?

• The force applied to an object

• The distance covered by an object

• The speed of something in a given direction

• The time taken for an object to move from one place to another

What is force?

• The energy an object has due to its motion

• Any influence that causes an object to change its movement or direction

• The speed at which an object moves in a particular direction

• The distance an object travels per unit of time
