What is the formula for calculating average speed?

Back

Average Speed = Total Distance / Total Time

Front

A dog runs 60 m in 20 s and then 40 m in 20 s. What is the total distance covered?

Back

Total Distance = 60 m + 40 m = 100 m

Front

A dog runs 60 m in 20 s and then 40 m in 20 s. What is the total time taken?

Back

Total Time = 20 s + 20 s = 40 s

Front

What is the average speed of the dog if it runs 100 m in 40 s?

Back

Average Speed = 100 m / 40 s = 2.5 m/s

Front

What happens to the kinetic energy of particles when a substance is cooled?

Back

Kinetic energy decreases.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion.

Front

What is the relationship between temperature and kinetic energy of particles?

Back

As temperature decreases, kinetic energy of particles decreases.

Front

What does a thicker arrow in a force diagram indicate?

Back

A thicker arrow indicates a greater force.

Front

What is the force of gravity?

Back

The force of gravity is the attraction between two masses.

Front

How does mass affect the force of gravity?

Back

Greater mass results in a stronger gravitational force.
