Exam Questions & 100% Correct Answers | Latest Update
2026 | Physics Exam Prep
1. If a crate has a mass of 50 kg and the coefficient of static friction between the
crate and the surface is 0.4, what is the maximum static friction force that can
act on the crate?
100 N
250 N
150 N
200 N
2. What is the primary distinction between weight and mass in physics?
Mass is the force exerted by gravity, while weight is a measure of
volume.
Weight and mass are identical and interchangeable terms.
Weight is constant regardless of location, while mass varies with
gravity.
Weight is the force exerted by gravity on an object, while mass is
the amount of matter in the object.
3. If its distance to the Sun were halved, the gravitational force on Jupiter due to
the Sun would
be 4 times its present value.
stay the same.
be 16 times its present value.
be 2 times its present value.
,4. A 25kg boy is riding a merry-go-round with a radius of 5m.
What is the centripetal force on the boy if his velocity is 6ms?
180N
150N
120N
196N
5. What is the unit of force used in the provided question about the factory
worker's push?
Watt
Newton
Joule
Pascal
6. If a crate experiences a frictional force of 200 N opposing the worker's push
of 635 N, what is the net force acting on the crate?
635 N
200 N
435 N
835 N
7. Inertia is the tendency for an object to
come down after being thrown into the air
follow a circular motion path
continue its current motion unless acted on by an outside force
, travel in a parabola
8. What is the term used to describe the force that acts perpendicular to a
surface in contact with an object?
Field Force
Tension Force
Elastic Force
Normal Force
9. What is the term used to describe the force that opposes the relative motion
of two surfaces in contact?
Tension
Inertia
Friction
Gravity
10. What is the formula used to calculate the acceleration due to gravity on a
celestial body?
g = M / (G * r)
g = M * r^2 / G
g = G * M / r^2
g = G * r^2 / M
11. If a person pushes against a wall with a force of 50 N, what force does the
wall exert back on the person according to the Law of Interaction?
100 N
, 0N
50 N
25 N
12. Describe the significance of the normal force in the context of a box resting
on the floor.
The normal force is irrelevant when the box is at rest.
The normal force counteracts the weight of the box, preventing it
from accelerating downward.
The normal force is the force that causes the box to slide.
The normal force increases the weight of the box.
13. Which of the following statements best describes surface friction?
c. Neither A nor B is true
b. When a person tries to move a crate by pushing it, and it does not
move, the crate has static friction acting on it.
d. Both A and B are true
a. When a person slides a crate across the floor and the crate does
move, the crate has kinetic friction acting on it.
14. What is the formula used to calculate the gravitational force between two
masses?
F=p*v
F = G * (m1 * m2) / r^2
F=m*a
F=m*g
