What is Newton's First Law of Motion?
Objects in motion stay in motion or an object at rest stays at rest unless acted upon by an external force.
The acceleration of an object is directly proportional to the net force acting on the object.
For every action, there is an equal and opposite reaction.
The force of gravity is the only force acting on falling objects.
If the net force on a moving object is zero, what can we say about the object's motion?
The object is accelerating.
The object is slowing down.
The object has constant velocity.
The object is changing direction.
Which of the following is the correct formula for Newton's Second Law?
F=m×a
a=F×m
F=am
a=mF
What is Newton's Third Law?
For every action, there is an equal and opposite reaction.
The bigger mass will always exert a bigger force.
An object at rest stays at rest.
Acceleration is due to gravity only.
What is acceleration?
The rate at which velocity changes over time.
The speed of an object in a given direction.
The distance traveled by an object.
The force applied to an object.
An object has a constant force is applied to it, what will happen to the object's acceleration (Hint: a=F/m)?
The acceleration will decrease.
The acceleration will increase.
The acceleration will remain constant.
The object will not accelerate.
What is momentum?
The force applied to an object.
A quantification of Inertia
The rate of change of velocity.
The resistance to change in motion.
How can the momentum of an object be increased?
By decreasing its mass.
By increasing its velocity.
By decreasing its velocity.
By increasing its mass and decreasing its velocity.
What happens to the total momentum of an object in the absence of external forces?
It increases.
It decreases.
It remains constant.
It becomes zero.
According to Newton's Second Law, if you double the force applied to an object, what happens to the acceleration?
It halves.
It remains the same.
It doubles.
It quadruples.
What does it mean when we say a force is a "net force"?
It is the only force acting on an object.
It is the sum of all the forces acting on an object.
It is a force that does not cause acceleration.
It is the strongest force acting on an object.
If an object is moving at a constant velocity, what can we infer about the net force acting on it?
The net force is increasing and unbalanced.
The net force is zero and is balanced.
The net force is acting in the direction of motion and is balanced.
The net force is acting opposite to the direction of motion and in unbalanced.
What unit is used for force?
Kilogram (kg)
Meter per second squared (m/s 2 )
Newton (N)
Joule (J)
