M2 Additional Final 1

Which of the following is an example of a scalar quantity?

• Force

• Velocity

• Mass

• Acceleration

If a car travels 200km north in 2 hours, what is its velocity?

• 100km/h north

• 200km/h south

• 400km/h north

• 50km/h north

What does it mean if an object is in uniform motion?

• It is accelerating

• It is decelerating

• It moves with constant speed in a straight line

• It is changing direction constantly

How does mass affect the gravitational force between two objects?

• The greater the mass, the weaker the gravitational force

• The greater the mass, the stronger the gravitational force

• Mass does not affect gravitational force

• The gravitational force is the same regardless of mass

In which direction does friction act?

• In the same direction as motion

• Opposite to the direction of motion

• Perpendicular to the direction of motion

• At a 45-degree angle to the direction of motion

What does Newton's First Law of Motion state?

• Force equals mass times acceleration

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

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

• Energy cannot be created or destroyed

Which of the following best describes inertia?

• The tendency of an object to resist a change in motion

• The rate at which an object changes its velocity

• The force exerted by gravity on an object

• The energy stored in an object due to its position

What is the unit of force in the SI system?

• Joule

• Newton

• Watt

• Pascal

Which of these is a non-contact force?

• Friction

• Air resistance

• Gravity

• Applied force

What happens to an object’s speed if the net force acting on it is zero?

• It accelerates

• It decelerates

• It moves with constant speed

• It stops immediately
