What is a force?
A force is a measurement of speed.
A force is an interaction that causes a change in motion.
A force is a fixed quantity that cannot change.
A force is a type of energy.
Which of the following is a contact force?
Gravity
Magnetism
Electricity
Friction
What type of force opposes motion between two surfaces?
Friction
Magnetism
Tension
Gravity
What is the effect of friction on motion?
Friction only affects stationary objects.
Friction has no effect on motion whatsoever.
Friction increases the speed of moving objects.
Friction opposes motion and can slow down or stop moving objects.
Which of the following is an example of balanced forces?
A balloon rising in the air
A book resting on a table
A person pushing a heavy box
A car accelerating on a highway
What happens when forces are unbalanced?
The object will remain at rest.
The object will stop moving immediately.
The object will accelerate in the direction of the net force.
The object will move in a circular path.
Which type of force is gravity?
Gravity is a fundamental force.
Gravity is a frictional force.
Gravity is a nuclear force.
Gravity is an electromagnetic force.
What is the unit of force?
newton (N)
joule (J)
watt (W)
pascal (Pa)
How does increasing the surface area affect friction?
Friction is only affected by weight, not surface area.
Increasing the surface area typically increases friction.
Surface area has no effect on friction.
Increasing the surface area decreases friction.
What is the role of friction in everyday life?
Friction increases speed and efficiency of machines.
Friction has no impact on movement or safety.
Friction is only a hindrance in all situations.
Friction enables movement control, prevents slipping, and allows machines to function.
Which of the following is NOT a type of friction?
Fluid friction
Static friction
Magnetic friction
Kinetic friction
What can be done to reduce friction?
Use heavier materials
Apply lubricants and use smoother surfaces.
Increase surface roughness
Apply heat to the surfaces
