3rd EoUT 3 Revision Quizz

Finish the sentence: A scalar has…

• direction only
• magnitude only
• magnitude and direction
• magnitude and distance

Answer explanation

Jupiter is a gas giant made primarily of hydrogen and helium. Unlike terrestrial planets that have solid surfaces, gas giants like Jupiter don't have a well-defined solid surface, allowing them to accumulate more mass in a gaseous form. This composition has allowed Jupiter to grow significantly larger than planets with solid surfaces.

Finish the sentence: A vector has…

• direction only
• magnitude only
• magnitude and direction
• magnitude and distance

Define resultant force

• The force applied to an object, eg. Pushing
• The correct force
• Forces in opposite directions added, and forces in the same direction subtracted
• The overall force

True or false: You can find the resultant force of non-parallel forces (at GCSE)

• True
• False

What direction do resistive forces (like friction or air resistance) act?

• Same as the direction of movement
• Opposite to direction of movement
• Perpendicular to direction of movement
• Parallel to direction of movement

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

• Force = mass + acceleration
• Force = mass ÷ acceleration
• Force = acceleration ÷ mass
• Force = mass × acceleration

What is the relationship between F, m, and a?

• F = m + a
• F = m ÷ a
• F = a ÷ m
• F = m × a

What is the unit of mass?

• m
• N
• g
• kg

Finish the sentence: If resultant force on an object increases, acceleration ______

• increases
• decreases
• stays the same
• is zero

Finish the sentence: If resultant force on an object decreases, acceleration ______

• increases
• decreases
• stays the same
• is zero
