1.

What does it mean for an object to be in equilibrium?

a)

An object is in equilibrium when the net force acting on it is zero, resulting in no change in motion.

b)

An object is in equilibrium when it is at rest and not moving at all.

c)

An object is in equilibrium when it is moving at a constant speed in a straight line.

d)

An object is in equilibrium when the forces acting on it are unbalanced.

2.

What happens to an object when forces are balanced?

a)

The object accelerates in the direction of the net force.

b)

The object remains at rest or continues to move at a constant velocity.

c)

The object experiences an increase in speed.

d)

The object changes direction abruptly.

3.

What is Newton's 1st Law of Motion?

a)

An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

b)

An object will accelerate in the direction of the net force acting on it.

c)

For every action, there is an equal and opposite reaction.

d)

An object in motion will eventually come to a stop unless acted upon by a force.

4.

What is Newton's 2nd Law of Motion?

a)

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. (F = ma)

b)

The force acting on an object is equal to the mass of the object multiplied by its velocity. (F = mv)

c)

An object in motion stays in motion unless acted upon by an external force. (Newton's 1st Law)

d)

For every action, there is an equal and opposite reaction. (Newton's 3rd Law)

5.

What is the formula for calculating force?

a)

Force (F) = mass (m) × acceleration (a)

b)

Force (F) = mass (m) + acceleration (a)

c)

Force (F) = mass (m) / acceleration (a)

d)

Force (F) = mass (m) - acceleration (a)

6.

How does friction affect motion?

a)

Friction increases the speed of an object.

b)

Friction has no effect on motion.

c)

Friction is a force that opposes motion, often causing an object to slow down or stop.

d)

Friction only affects objects in water.

7.

What is an example of inertia?

a)

A passenger lurching forward in a car when it suddenly stops.

b)

A ball rolling down a hill.

c)

A person pushing a heavy object.

d)

A leaf falling from a tree.

8.

What is inertia?

a)

The tendency of an object to resist changes in its state of motion.

b)

The force that causes an object to accelerate.

c)

The mass of an object multiplied by its velocity.

d)

The energy stored in an object due to its position.

9.

What is the significance of the net force?

a)

It is the total force acting on an object, determining its acceleration.

b)

It is the force that opposes motion.

c)

It is the force that acts only on stationary objects.

d)

It is the force that is always equal to zero.

10.

What is Newton's 3rd Law of Motion?

a)

For every action, there is an equal and opposite reaction.

b)

An object in motion stays in motion unless acted upon by an external force.

c)

The force of gravity is proportional to the mass of the objects involved.

d)

For every force, there is a reaction force that is equal in size and opposite in direction.

11.

What does 'unbalanced forces' mean?

a)

Forces that are equal in size and opposite in direction, resulting in no change in motion.

b)

Forces that are not equal in size and opposite in direction, resulting in a change in motion.

c)

Forces that act on an object but do not affect its motion.

d)

Forces that are equal in size and act in the same direction, resulting in a change in motion.

12.

Can an object be in motion if no forces are acting on it?

a)

No, it must be acted upon by a force to move.

b)

Yes, an object can continue moving at a constant velocity if no net forces act on it.

c)

Only if it was previously in motion.

d)

Yes, but only in a vacuum.

13.

What is the relationship between force, mass, and acceleration?

a)

Force is the product of mass and acceleration; increasing mass requires more force to achieve the same acceleration.

b)

Force is independent of mass and acceleration.

c)

Mass is the product of force and acceleration.

d)

Acceleration is the product of force and mass.

14.

What is an example of Newton's 3rd Law in action?

a)

When you jump off a small boat, you push the boat backward as you move forward.

b)

A ball thrown in the air comes back down due to gravity.

c)

A car accelerates when the driver presses the gas pedal.

d)

A person pushes against a wall and does not move.

15.

How does mass affect acceleration according to Newton's 2nd Law?

a)

A larger mass requires a greater force to achieve the same acceleration as a smaller mass.

b)

Mass has no effect on acceleration; it is only dependent on force.

c)

A smaller mass requires more force to achieve the same acceleration as a larger mass.

d)

Acceleration is inversely proportional to mass, meaning more mass results in less acceleration.
