It is decreasing.
It is increasing.
It is zero.
#3
What is the formula for average speed?
Speed = Distance/Time
Speed = Time/Distance

#4
Which of the following is an example of projectile motion?
A car accelerating on a straight road
A ball thrown into the air
A person walking in a circle
A boat moving in a river
#5
What is the unit of force in the International System of Units (SI)?
#6
What is the law of inertia?
An object at rest stays at rest, and an object in motion stays in motion with constant velocity unless acted on by a net external force.
The force acting on an object is equal to the mass of the object multiplied by its acceleration.
For every action, there is an equal and opposite reaction.
The gravitational force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
#7
What does the term 'displacement' refer to in physics?
The change in position of an object
The total distance traveled by an object
The speed of an object
The force applied to an object
#8

A car moving on a straight road
A satellite orbiting Earth
A ball rolling down a hill
A person walking in a straight line
#9
Which of Newton's laws states that an object at rest will stay at rest, and an object in motion will stay in motion with the same speed and in the same direction unless acted on by an unbalanced external force?
Newton's First Law
Newton's Second Law
Newton's Third Law
Newton's Law of Universal Gravitation
#10

The total energy of an isolated system remains constant over time.
Energy is always decreasing in a closed system.
Energy is directly proportional to mass.
#17

The net force is zero.
The net force is constant.
The net force is increasing.
The net force is decreasing.
#18
