[YEAR 7 SCIENCE]: AFL - Forces

What is friction?

• Force that opposes motion

• Force that supports motion

• Force that has no effect on motion

• Force that causes motion

Which force pulls objects towards the center of the Earth?

• magnetism

• friction

• electricity

• gravity

What is the force that attracts or repels objects?

• electromagnetic force

• frictional force

• nuclear force

• gravitational force

What is the overall force acting on an object when all the individual forces are added together?

• net force

• sum force

• combined force

• total force

When two forces acting on an object are equal in size and opposite in direction, what is the resulting force called?

• friction

• equilibrium

• acceleration

• unbalance

Which force opposes the motion of objects that are in contact with each other?

• gravity

• magnetism

• friction

• inertia

What is the force that keeps objects on the ground and prevents them from floating away?

• friction

• gravity

• magnetism

• buoyancy

What is the force that allows magnets to attract or repel other objects?

• magnetic force

• friction

• electric force

• gravity

When the forces acting on an object are balanced, what is the net force?

• zero

• infinity

• negative

• positive

When the forces acting on an object are unbalanced, what is the net force?

• The net force is the vector sum of all the individual forces.

• The net force is the sum of all the individual forces squared.

• The net force is the average of all the individual forces.

• The net force is the difference between the largest and smallest individual forces.
