Physics A Course Assessment

Front

What is displacement?

Back

Displacement is a vector quantity that refers to the change in position of an object. It has both magnitude and direction.

Front

What type of quantity is distance?

Back

Distance is a scalar quantity that refers to the total path length traveled by an object, regardless of direction.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that measures how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What does it mean if an object is not moving?

Back

If an object is not moving, its displacement is zero, and it is at rest relative to a reference point.

Front

What happens to heat energy when you touch a cold object?

Back

When you touch a cold object, heat energy is transferred from your hand to the object, making your hand feel colder.

Front

What is the SI unit of distance?

Back

The SI unit of distance is the meter (m).

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It is a vector quantity and can be measured in meters per second squared (m/s²).

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion, calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.
