What is displacement in physics?
The total distance traveled by an object
The shortest distance from the initial to the final position of a moving object
The time taken for an object to move from one point to another
The speed of an object in a given direction
What is the formula for calculating average speed?
Total distance divided by total time
Total time divided by total distance
Total distance multiplied by total time
Total time minus total distance
What does a horizontal line represent on a position vs. time graph?
The object is moving at a constant speed
The object is accelerating
The object is at rest
The object is moving backward
What is Newton's First Law of Motion?
An object at rest will stay at rest, and an object in motion will stay in motion, unless acted upon by a net force.
An object will accelerate in the direction of the net force applied to it.
For every action, there is an equal and opposite reaction.
The force of gravity acts between all masses.
What is the formula for Newton's Second Law of Motion?
F = ma
F = m/a
F = m + a
F = a/m
According to Newton's Second Law, if the mass of an object increases, what happens to the force required to accelerate it at the same rate?
The force increases
The force decreases
The force remains the same
The force becomes zero
If the forces are equal, why does the bug accelerate more than the truck?
The bug is more aerodynamic than the truck.
The mass of the bug is much less than the mass of the truck.
The truck is moving uphill.
The bug has more friction with the air.
What is mass?
The force exerted on an object due to gravity.
The amount of matter in an object.
The volume of an object.
The density of an object.
What is weight?
The amount of matter in an object.
The volume of an object.
The force exerted on an object due to gravity.
The density of an object.
What is the weight of a 50 kg person on Earth?
490 N
185 N
80 N
50 N
What is kinetic energy?
Energy due to an object's position
Energy due to motion
Energy stored in chemical bonds
Energy from the sun
What is potential energy?
Energy due to motion
Energy from nuclear reactions
Energy due to an object's position
Energy from sound waves
What are the two factors that determine gravitational force?
Mass & Distance
Speed & Time
Volume & Pressure
Temperature & Humidity
What happens to particles when they are heated?
They move faster.
They move slower.
They stop moving.
They change color.
What is magnetism caused by?
Movement of electrons
Movement of protons
Movement of neutrons
Movement of atoms
At what speed does all electromagnetic radiation travel?
299,792,458 m/s
150,000,000 m/s
1,000,000 m/s
300,000 m/s
Which of the following is an example of a longitudinal wave?
Light Waves
Sound Waves
Radio Waves
Microwaves
What is the term for the bending of light as it passes from one substance to another?
Reflection
Diffraction
Refraction
Absorption
How are frequency and wavelength related?
Directly related
Inversely related
Not related
Proportionally related
In a "closed system," what happens to the total energy in the system?
It is lost to the surroundings.
It is conserved, although it may change forms.
It increases over time.
It decreases over time.
What happens to an object if there is a net force acting on it?
It changes its motion
It remains stationary
It decreases in size
It changes color
What is the acceleration of an object moving at constant speed?
Zero
Increasing
Decreasing
Constant
