Physics Quiz for Grade 5

What is a scalar quantity?

• A quantity with only magnitude

• A quantity with magnitude and direction

• A quantity that can be derived from other quantities

• A quantity that cannot be derived from other quantities

What does Newton's First Law state?

• For every action, there is an equal and opposite reaction

• The rate of change of momentum is directly proportional to the applied force

• The gravitational force between two bodies is inversely proportional to the square of the distance between them

• An object will remain at rest or in uniform motion unless acted upon by an external force

What is the definition of momentum?

• The product of mass and velocity

• The force applied over time

• The rate of change of velocity

• The energy of an object in motion

What does the term 'inertia' refer to?

• The speed of an object in a straight line

• The tendency of an object to resist changes in its state of motion

• The energy stored in an object due to its position

• The force that causes an object to accelerate

What is the formula for calculating speed?

• Speed = Force / Mass

• Speed = Mass / Acceleration

• Speed = Time / Distance

• Speed = Distance / Time

What is the unit of force?

• Joule

• Watt

• Newton

• Pascal

What does the term 'thermal equilibrium' mean?

• Heat is lost to the environment

• Heat is generated by friction

• Heat flows from a cooler object to a warmer object

• No heat transfer occurs between two objects

What is the principle of Pascal?

• The buoyant force on an object is equal to the weight of the fluid displaced

• Pressure applied to a confined fluid is transmitted undiminished in all directions

• The pressure of a gas decreases as its volume increases

• The temperature of a gas is directly proportional to its volume

What is the definition of frequency?

• The time taken for one complete cycle

• The number of complete cycles per second

• The distance between two waves

• The maximum displacement of a wave

What is the formula for calculating pressure?

• Pressure = Volume / Mass

• Pressure = Mass / Volume

• Pressure = Area / Force

• Pressure = Force / Area
