Q1
Easy
Which type of force is applied when you push a book across a table?
A. Frictional Force
B. Gravitational Force
C. Magnetic Force
D. Electrostatic Force
Show Answer & Explanation
Correct Answer: A
Frictional force opposes the motion of objects sliding over each other, like a book across a table.
Q2
Easy
What is the force called that pulls objects toward the earth?
A. Magnetic Force
B. Frictional Force
C. Gravitational Force
D. Tension Force
Show Answer & Explanation
Correct Answer: C
Gravitational force is the attractive force that pulls objects toward the Earth due to its mass.
Q3
Easy
Which type of force is produced when two magnets repel each other?
A. Friction Force
B. Magnetic Force
C. Elastic Force
D. Contact Force
Show Answer & Explanation
Correct Answer: B
Magnetic force is responsible for the repulsion or attraction between magnets based on their poles.
Q4
Medium
Which of the following forces can act at a distance without contact?
A. Frictional force
B. Gravitational force
C. Tension force
D. Normal force
Show Answer & Explanation
Correct Answer: B
Gravitational force acts at a distance, whereas the other forces listed require contact.
Q5
Medium
If the mass of an object is doubled, what happens to the gravitational force acting on it?
A. It remains the same
B. It doubles
C. It triples
D. It halves
Show Answer & Explanation
Correct Answer: B
The gravitational force is directly proportional to mass; thus, doubling the mass doubles the force.
Q6
Medium
Which of the following is an example of contact force?
A. Magnetic force
B. Electrostatic force
C. Frictional force
D. Gravitational force
Show Answer & Explanation
Correct Answer: C
Frictional force requires direct contact between surfaces to act, unlike the other forces listed.
Q7
Medium
What is the net force acting on an object if two equal forces of 10 N act in opposite directions?
A. 0 N
B. 10 N
C. 20 N
D. 5 N
Show Answer & Explanation
Correct Answer: A
When equal forces act in opposite directions, they cancel each other out, resulting in a net force of 0 N.
Q8
Hard
What type of force acts on an object when it is at rest on a surface?
A. Frictional Force
B. Gravitational Force
C. Normal Force
D. Magnetic Force
Show Answer & Explanation
Correct Answer: C
The normal force acts perpendicular to the surface, supporting the object against gravity and preventing it from sinking into the surface.
Q9
Hard
Which of the following forces can change the state of motion of an object?
A. Balanced Forces
B. Unbalanced Forces
C. Centripetal Force
D. Electrostatic Force
Show Answer & Explanation
Correct Answer: B
Unbalanced forces are necessary to change the state of motion, as they result in net force acting on the object.
Q10
Hard
If you double the mass of an object while keeping the force constant, what happens to the acceleration?
A. It doubles
B. It halves
C. It remains the same
D. It quadruples
Show Answer & Explanation
Correct Answer: B
According to F = ma, if mass increases while force is constant, acceleration decreases by half.
