Science Forces

Question 1

What is a force?

Answer 1

A force is a push or pull exerted on an object.

Question 2

True or False: Forces can only be applied in one direction.

Answer 2

False

Question 3

Fill in the blank: The unit of force in the International System of Units (SI) is the _______.

Answer 3

Newton

Question 4

What is the formula for calculating force?

Answer 4

Force = Mass × Acceleration (F = ma)

Question 5

Which of the following is NOT a type of force? A) Gravitational B) Frictional C) Electromagnetic D) Thermal

Answer 5

D) Thermal

Question 6

Short answer: What is gravitational force?

Answer 6

Gravitational force is the attraction between two masses.

Question 7

True or False: Frictional force always acts in the opposite direction to the motion of the object.

Answer 7

True

Question 8

What is the effect of balanced forces on an object?

Answer 8

Balanced forces do not change the object’s motion.

Question 9

What type of force is responsible for the acceleration of an object?

Answer 9

Unbalanced force

Question 10

Fill in the blank: The force of gravity on an object is also known as its _______.

Answer 10

Weight

Question 11

What is the relationship between mass and weight?

Answer 11

Weight is the mass of an object multiplied by the acceleration due to gravity.

Question 12

True or False: All forces have both magnitude and direction.

Answer 12

True

Question 13

What is friction?

Answer 13

Friction is a force that opposes the relative motion of two surfaces in contact.

Question 14

Multiple choice: Which force is responsible for keeping planets in orbit around the sun? A) Electromagnetic B) Gravitational C) Nuclear D) Frictional

Answer 14

B) Gravitational

Question 15

What is air resistance?

Answer 15

Air resistance is a type of frictional force that acts against the motion of an object moving through air.

Question 16

Fill in the blank: The force that pulls objects toward the center of the Earth is called _______.

Answer 16

gravity

Question 17

Short answer: What is tension force?

Answer 17

Tension force is the pulling force transmitted through a string, rope, or cable when it is pulled tight.

Question 18

What is the difference between contact and non-contact forces?

Answer 18

Contact forces require physical contact between objects, while non-contact forces act at a distance.

Question 19

True or False: The stronger the force applied to an object, the greater the acceleration.

Answer 19

True

Question 20

What is the net force?

Answer 20

The net force is the total force acting on an object after all the forces are combined.
