Total questions: 25
Worksheet time: 13mins
What is the study of physics primarily concerned with?
Past civilizations
Shapes and colors
Matter, energy, and their interactions
Animals and ecosystems
Which of the following is a scalar quantity?
Displacement
Velocity
Distance
Force
Which of the following is a vector quantity?
Speed
Distance
Time
Velocity
What does the formula speed = distance ÷ time calculate?
Direction
Velocity
Speed
Mass
If an object travels 80 meters in 20 seconds, what is its speed?
4 m/s
2 m/s
0.25 m/s
100 m/s
What does displacement measure?
Total time
Total path traveled
Straight-line change in position
Average force
What does acceleration describe?
A change in color
A change in velocity
Distance moved
Object’s mass
What is the formula for acceleration?
a = v × t
a = d ÷ t
a = (v_f - v_i) ÷ t
a = m × a
The unit for acceleration is:
m/s
m²
m/s²
km/h
A car goes from 10 m/s to 30 m/s in 4 seconds. What is its acceleration?
10 m/s²
5 m/s²
2.5 m/s²
20 m/s²
A horizontal line on a speed-time graph represents:
Changing acceleration
No motion
Constant speed
Decreasing speed
What does the slope of a position-time graph represent?
Acceleration
Direction
Speed
Mass
Which graph best shows acceleration?
Position vs. mass
Speed vs. time
Distance vs. temperature
Mass vs. volume
Newton’s First Law is also called the law of:
Action
Force
Energy
Inertia
What happens to an object at rest with no net force acting on it?
It moves upward
It begins to rotate
It stays at rest
It accelerates forward
What is the formula for Newton’s Second Law?
F = m + a
F = m × a
F = a ÷ m
F = m ÷ a
What is the unit of force?
Joule
Kilogram
Watt
Newton
Newton’s Third Law states:
Acceleration increases with speed
For every action, there is an equal and opposite reaction
Force equals mass times acceleration
Objects at rest stay at rest
Which of the following is an example of Newton’s Third Law?
A pencil resting on a table
A soccer ball sitting still
A rocket lifting off the ground
An object falling from a table
What is a fluid?
Only water
Any substance that flows
Only liquids
A rigid solid
Which of the following is a fluid?
Ice cube
Wood block
Steam
Rock
What is buoyancy?
Downward force on an object
Sideways pull of friction
Upward force exerted by a fluid
Energy in motion
Archimedes' Principle states that:
Density equals mass divided by volume
Force equals mass times acceleration
Buoyant force equals the object's weight
Buoyant force equals weight of displaced fluid
If an object floats in water, it is:
More dense than water
Less dense than water
A ship floats on the ocean because:
It's made of plastic
It generates electricity
It displaces more water than it weighs
It uses friction to stay afloat
