Physical Science Semester 1 Review

What is the process called when particles in a substance gain energy and move faster?

• Speeding Up (related to melting)

• Cooling Down (related to freezing)

• Condensation (related to gas to liquid)

• Sublimation (related to solid to gas)

What happens to the temperature of a substance during a phase change?

• The temperature increases steadily.

• The temperature decreases steadily.

• The temperature remains constant during a phase change.

• The temperature fluctuates randomly.

What is the term for the energy stored in an object due to its position or configuration?

• Kinetic Energy

• Thermal Energy

• Potential Energy

• Chemical Energy

What is the unit of measurement for force?

• Pascal (Pa)

• Joule (J)

• Newton (N)

• Watt (W)

What is the term for the shortest distance from the starting point to the ending point, regardless of the path taken?

• Distance

• Displacement

• Path Length

• Total Travelled Distance

What is the term for the change in velocity over time?

• Velocity

• Acceleration

• Speed

• Momentum

How do you calculate acceleration?

• Acceleration = (Final Velocity + Initial Velocity) / Time

• Acceleration = (Final Velocity - Initial Velocity) / Time

• Acceleration = Final Velocity / Time

• Acceleration = Initial Velocity / Time

What is the principle that states that energy cannot be created or destroyed, only transformed?

• Law of Conservation of Energy

• First Law of Thermodynamics

• Second Law of Thermodynamics

• Law of Energy Transformation

What is the formula for calculating momentum?

• Momentum = Mass + Velocity

• Momentum = Mass - Velocity

• Momentum = Mass x Velocity

• Momentum = Mass / Velocity

What is the effect of mass on gravitational force?

• The greater the mass, the greater the gravitational force.

• Mass has no effect on gravitational force.

• The greater the mass, the weaker the gravitational force.

• Gravitational force is only affected by distance, not mass.
