Physics Forces Revision

Question 1

What Is Weight?

Answer 1

A force on an object due to the gravitational pull on another object.

Question 2

What Is Air Resistance

Answer 2

A resistive Force due to the collision with air particles which always happens in the opposite direction of motion

Question 3

What is friction?

Answer 3

A resistive force due to two surfaces rubbing against each other which always acts in the opposite direction of motion

Question 4

What is the normal contact Force

Answer 4

The force which is when a surface exerts to an object when in contact with each other.

Question 5

What Is Tension

Answer 5

A force acting on an object due to the change in shape (compression and extension)

Question 6

What is Magnetism

Answer 6

A force on an object due to a magnetic field.

Question 7

What Is Electrostatic?

Answer 7

A force on charged objects due to an electrostatic field.

Question 8

What Is Buoyancy?

Answer 8

A force on an object due to the pressure of liquid.

Question 9

What Is Newton’s Second Law?

Answer 9

Force = mass x acceleration(m/s squared)

Weight = mass x gravitational pull which on earth is 9.8 m/s squared
