Which force acts on an object to pull it towards the center of the Earth?

• magnetism

• friction

• repulsion

• gravity

What force acts perpendicular to the surface when an object is placed on a table?

• Normal force

• Frictional force

What type of force is present in a rope or string that is pulled taut?

• Tension

• Gravity

• Friction

• Compression

Which force is exerted by a spring when it is stretched or compressed?

• Frictional force

• Pulling force

• Pushing force

• Restoring force

What is the formula to calculate frictional force?

• Frictional Force = Work / Distance

• Frictional Force = Mass x Acceleration

• Frictional Force = Coefficient of Friction x Normal Force

• Frictional Force = Tension x Angle

What is the SI unit of gravitational force?

• Newton (N)

• Meter (m)

• Kilogram (kg)

• Joule (J)

In which direction does the normal force act on an object placed on a flat surface?

• downward

• upward

• sideways

What is the tension force in a rope supporting a hanging object?

• Half the weight of the hanging object

• Equal to the weight of the hanging object

• Unrelated to the weight of the hanging object

• Double the weight of the hanging object

What is the relationship between the force applied to a spring and its extension?

• The force applied to a spring is directly proportional to its extension.

• The force applied to a spring is inversely proportional to its extension.

• The force applied to a spring causes random extension changes.

• The force applied to a spring has no effect on its extension.
