# Friction Quiz For Grade 2

Explanation:

Introduction: ⁢
Are you‌ looking for⁤ questions to make your grade 2 ‍students understand⁢ the concept of friction?⁢ Look no further, this ‍friction quiz for grade 2, provides ​twenty interesting questions that would surely help your students understand the concept of friction. Let’s begin!

Q1:‌ What is friction?
Options:
A:⁣ The force⁣ of gravity between ​two objects⁤
Magnetism between two objects
C: The force ​that resists motion between​ two objects ‍when ‍they come into contact
D: The​ force⁤ of ⁢air⁤ between two objects

Explanation: Friction is the force that ⁢resists motion⁤ between two objects when⁣ they ⁢come into contact.

Q2: ‌What are the two types of friction?
Options:
A:​ Rolling and slipping
B: Air and water
C: Gravity and magnetism
D: Static and sliding

Explanation: There are two ⁤types of friction, static⁢ and sliding.

Q3: What happens when you increase the frictional ⁣force?
Options:
A: The ​speed of the object⁢ increases⁣
B: The ⁢speed of the⁢ object decreases
C: ‌The object ‌moves faster
D: The object moves slower

Explanation: When ⁤you increase⁣ the frictional force, the ​object moves slower.

Q4: How does friction ‍affect the motion of an ​object?
Options:
A: ​It decreases the motion of the object
B: It increases the motion of the⁤ object ⁤
C: It prevents the object from moving
D: It makes the object move faster ⁢

Explanation: Friction affects the motion‌ of an object by decreasing​ its motion.

Q5: What ⁢is the effect of friction on⁢ the kinetic ‌energy of an object?
Options: ⁣
A: It increases the⁢ kinetic energy⁤ of an⁢ object
B: It decreases the kinetic‍ energy of an object⁣
C: It prevents the object from gaining energy⁣
D: It‌ makes the object move faster ⁤

Explanation: Friction decreases the kinetic energy of an⁤ object.

Q6: What happens to ⁤a rolling object when you increase the ‌frictional force?
Options:
A: It increases the speed ‌of the object
B: It decreases the speed of the object
C: It stops⁣ the object completely
D:‌ It prevents‌ the object from rolling

Explanation: When ‍you increase the frictional force, the speed of the rolling object‌ decreases.

Q7: Does friction occur in a vacuum?
Options:⁣
A: Yes
B: No
C: Depends​ on the air pressure
D: ⁣Depends​ on the force of ⁢the object

Explanation: Friction does not occur in⁢ a vacuum. ⁤

Q8: What type of friction occurs when two surfaces are sliding against each⁣ other?
Options:
A: Static friction‍
B:‌ Rolling friction
C: Sliding friction
D: ​Air friction

Explanation: Sliding friction occurs when two surfaces are sliding against each other.

Q9: How does friction help while walking?
Options:
A: It helps‌ us stay balanced
B: It ‌helps us‌ move faster
C: It helps us stop
D:⁣ It ⁤helps us ‌jump higher

Explanation: ‌Friction helps us stop ⁢while walking. ‍

Q10: What type of friction occurs⁤ when two surfaces are in contact but not moving?​
Options:
A: Rolling friction
B: Sliding ‌friction
C: ‌Static friction
D: Air friction

Explanation: Static friction occurs when two⁢ surfaces are in contact but not moving.

Q11:⁣ Does friction cause an object to move? ​
Options:
A:​ Yes
B: No
C: Depends on the air⁢ pressure
D: Depends ‍on the force of the object

Explanation: Friction​ does not cause an object to move.

Q12: When two objects move ⁣in⁢ opposite directions, is​ friction produced?
Options:
A: Yes
B: No
C: Depends on the air pressure
D: Depends on the force of the⁤ object

Explanation: Friction is produced⁣ when two objects move in opposite directions.

Q13: What type of friction is produced when a body‌ is pushed on ⁢a horizontal surface? ⁣
Options:
A: Rolling friction
B: Air friction
C: Static friction ​
D: Sliding ⁤friction

Explanation: Static friction is produced when a⁣ body is⁣ pushed on a ⁢horizontal surface.‍

Q14: ⁢What ‌type of ⁤friction is produced when two ‍rough surfaces slide ​past each ⁢other? ⁢
Options: ⁣
A: Rolling friction
B: Air friction
C: Static friction ⁢
D: Sliding friction ⁣
