Total questions: 15
Worksheet time: 8mins
What is the unit used for measuring forces?
Kilogram (kg)
Pascal (Pa)
Joule (J)
Newton (N)
What force is responsible for pulling objects towards the Earth?
Gravity
Friction
Upthrust
Air resistance
What happens to the resultant force when it equals zero?
The forces are balanced
The object stops moving
The object moves faster
The object accelerates
What is the formula to calculate weight?
W = m/g
W = m - g
W = m + g
W = mg
What type of force opposes motion?
Gravity
Friction
Upthrust
Thrust
What is the pressure formula?
P = F/A
P = A/F
P = F + A
P = F - A
What is the effect of increasing the mass of an object on its acceleration?
Acceleration increases
Acceleration decreases
Acceleration remains the same
Acceleration becomes zero
What is the centripetal force?
Force that causes acceleration
Force that opposes gravity
Force that keeps an object moving in a circle
Force that causes friction
What is static friction?
Friction when an object is moving
Friction that occurs in gases
Friction that stops an object from moving
Friction that occurs in liquids
What happens to an object's weight on the Moon compared to Earth?
It increases
It decreases
It remains the same
It becomes zero
What is the relationship between force, mass, and acceleration?
F = m + a
F = a/m
F = m/a
F = ma
What is the elastic limit of a material?
The point where it breaks
The point where it stops stretching
The point where it returns to original shape
The point where it becomes permanently deformed
What is air resistance?
A force that pushes objects up
A force that opposes motion through air
A force that pulls objects down
A force that helps objects move
What does the term 'upthrust' refer to?
The force of air resistance
The force of friction
The upward push of a liquid or gas
The downward force of gravity
What is the effect of pressure in liquids as depth increases?
Pressure becomes zero
Pressure decreases
Pressure increases
Pressure remains constant
