Energy Force Work and Motion Test

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken. It is measured in meters per second (m/s).

Front

How do you calculate average speed?

Back

Average speed = Total distance / Total time.

Front

What is the unit for mass?

Back

Kilogram (Kg) is the unit for mass.

Front

What does a graph showing negative acceleration indicate?

Back

A graph showing negative acceleration indicates that an object is slowing down.

Front

What does a graph showing acceleration indicate?

Back

A graph showing acceleration indicates that an object is increasing its speed.

Front

What is density?

Back

Density is the mass of an object divided by its volume, typically expressed in grams per cubic centimeter (g/cm³).

Front

If the density of a substance remains the same when cut into pieces, what does this imply?

Back

It implies that density is an intrinsic property of the material and does not change with the size of the sample.

Front

What is the formula for calculating density?

Back

Density = Mass / Volume.

Front

What is the difference between speed and velocity?

Back

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

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's second law, Force = Mass x Acceleration (F = ma).
