Force & Pressure

gases exert pressure

• in all directions

• upwards

• downwards

• sideways

atmospheric pressure equals

• 1,00,000 pascals

• 1 pascal

• 1000 pascals

if we increase the surface area, pressure

• decreases

• increases

• remains the same

if we increase the perpendicular distance, moment of force (torque)

• increases

• decreases

• remains the same

the SI unit of thrust is

• N

• Nm

• Pa

• N/m²

if a body weighs 70 kgf, its mass is

• 70 kg

• 700 kg

• 7 kg

• 7000 kg

1 kgf equals

• 10 N

• 1 N

• 100 N

• 1000 N

the SI unit of torque is

• Nm

• N

• N/m²

• Pa

a force can change the shape & size of a body, if the body is

• non-rigid

• rigid

• just any body

anti-clockwise torque is considered

• positive

• negative
