Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken. It is measured in km/hr or m/s.

Front

How do you calculate average speed?

Back

Average speed = Total distance / Total time.

Front

What is the unit of weight?

Back

Weight is measured in Newtons (N).

Front

What is the unit of mass?

Back

Mass is measured in kilograms (kg).

Front

What is speed?

Back

Speed is the measure of the rate at which an object changes its position.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its speed or direction.

Front

What is net force?

Back

Net force is the total force acting on an object, taking into account all the individual forces.

Front

How do you determine net force?

Back

Net force is determined by adding all the forces acting on an object, considering their direction.

Front

What is the difference between weight and mass?

Back

Weight is the force exerted by gravity on an object, while mass is the amount of matter in an object.

Front

What is a reference frame?

Back

A reference frame is a perspective from which motion is observed and measured.
