Force and Motion Quiz

What is the primary cause of an object starting to move?

• Magnetism

• Gravity

• Force

• Friction

What happens when balanced forces act on an object?

• The object changes direction

• The object moves in a circle

• The object remains at rest

• The object accelerates

Which type of friction occurs when solid surfaces slide over each other?

• Static friction

• Rolling friction

• Fluid friction

• Sliding friction

What is the force that attracts all objects in the universe?

• Friction

• Gravity

• Magnetism

• Inertia

According to Newton's first law, what will an object at rest do if no unbalanced force acts on it?

• It will remain at rest

• It will change direction

• It will start moving

• It will accelerate

What does Newton's second law of motion relate force to?

• Mass and velocity

• Mass and acceleration

• Inertia and mass

• Speed and direction

What is inertia?

• The acceleration of an object

• The tendency of an object to resist changes in motion

• The force that pulls objects toward the Earth

• The speed of an object in a given direction

What happens to acceleration if the mass of an object increases, according to Newton's second law?

• Acceleration increases

• Acceleration becomes zero

• Acceleration decreases

• Acceleration remains the same

What does Newton's third law of motion state about forces?

• Forces occur in pairs that are equal and opposite

• Forces are always balanced

• Forces only act on stationary objects

• Forces are independent of mass

In the example of a baseball player hitting a ball, what does the ball experience?

• A change in mass

• A change in direction and speed

• An increase in mass

• A decrease in velocity
