Which of the following best describes Newton’s First Law of Motion?
An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an unbalanced force.
An object will always move unless stopped by friction.
An object in motion will eventually stop on its own.
An object at rest will start moving without any force.
How is an object's mass related to its inertia?
Objects with more mass have more inertia.
Objects with less mass have more inertia.
Mass does not affect inertia.
Only moving objects have inertia.
If you are riding a skateboard and it suddenly stops, what happens to your body?
You continue moving forward due to inertia.
You stop immediately with the skateboard.
You move backward.
You jump off the skateboard.
Why are seatbelts important in a car according to Newton’s First Law?
They provide the unbalanced force needed to stop your body’s forward motion.
They make the car go faster.
They help you steer the car.
They keep the car doors closed.
If you push a heavy shopping cart and a light shopping cart with the same force, which will have a smaller acceleration?
The heavy cart
The light cart
Both will have the same acceleration
Neither will accelerate
Which of the following is a correct calculation using F=ma if F=150 N and m=0.15 kg?
a = 1,000 m/s²
a = 10 m/s²
a = 22.5 m/s²
a = 0.01 m/s²
What is the main difference between mass and weight?
Mass is the amount of matter; weight is the force of gravity acting on that mass.
Mass changes depending on location; weight is constant everywhere.
Mass is measured in Newtons; weight is measured in kilograms.
Mass is only used on Earth; weight is used everywhere.
Which variable in the Second Law equation F=ma represents mass?
m
F
a
N
If a car suddenly stops, what provides the force to stop your body from moving forward?
The seatbelt
The car engine
The tires
The windshield
Which of the following is NOT true about mass?
Mass is constant everywhere.
Mass is the amount of matter in an object.
Mass changes depending on gravity.
Mass is used in the Second Law equation.
If the force applied to an object increases and mass stays the same, what happens to acceleration?
Acceleration increases
Acceleration decreases
Acceleration stays the same
Acceleration becomes zero
Which of the following statements about weight is correct?
Weight depends on the gravitational field.
Weight is the same everywhere.
Weight is the amount of matter in an object.
Weight is used in the Second Law equation.
Which of the following best describes Newton’s Third Law of Motion?
For every action, there is an equal and opposite reaction.
Objects in motion stay in motion unless acted upon by a force.
Force equals mass times acceleration.
Energy cannot be created or destroyed.
When a ball is sitting on the floor and not moving, which law explains why it stays at rest?
First Law (Inertia)
Second Law (F=ma)
Third Law (Action-Reaction)
Law of Conservation of Energy
In the context of dribbling a basketball, what is the “action” when the ball hits the floor?
The ball hitting the floor.
The player catching the ball.
The ball rolling away.
The ball changing color.
Which of the following statements about forces is true according to Newton’s Third Law?
Forces always occur in pairs.
Forces only act in one direction.
Forces can be created from nothing.
Forces are always unequal.
When a rocket launches, what is the action and reaction pair involved?
Action: Expelling hot gas downward; Reaction: Thrust pushes rocket upward.
Action: Rocket turns on lights; Reaction: Rocket moves forward.
Action: Rocket cools down; Reaction: Rocket slows down.
Action: Rocket changes color; Reaction: Rocket stops.
Why does the force you exert on the wall not cause the wall to move?
The wall’s mass and friction/inertia are too great to be overcome.
The wall is made of rubber.
The wall is too far away.
The wall is invisible.
If the floor exerts an equal and opposite upward force on you, what is this force called?
The normal force.
The friction force.
The gravitational force.
The magnetic force.
Which law explains why a ball accelerates faster when a greater force is applied?
Second Law (F=ma)
First Law (Inertia)
Third Law (Action-Reaction)
Law of Conservation of Energy
Which of the following best explains why a soccer ball moves forward when kicked?
The ball is attracted to the player's foot.
The ball moves on its own due to gravity.
The ball changes mass when kicked.
A force is applied to the ball, causing it to accelerate in the direction of the force.
What happens to the acceleration of an object if its mass increases but the applied force stays the same?
Acceleration increases
Acceleration decreases
Acceleration becomes zero
Acceleration stays the same
When you jump off a small boat onto a dock, why does the boat move backward?
The water pushes the boat forward.
The boat is heavier than you.
The boat is pulled by the dock.
Because of Newton’s Third Law: your action of jumping forward causes an equal and opposite reaction on the boat.
