Physics Final MS Quiz

What is the formula for speed?

• Distance × time

• Distance ÷ time

• Time ÷ distance

• Velocity × time

What does the slope of a velocity-time graph represent?

• Speed

• Acceleration

• Distance

• Displacement

An object is moving at a constant speed. What can you infer about its net force?

• The net force is positive

• The net force is negative

• The net force is zero

• The object is accelerating

According to Newton’s Second Law, if the force acting on an object is doubled, its acceleration will:

• Double

• Stay the same

• Be halved

• Be squared

What does Newton’s Third Law state?

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

• Force equals mass times acceleration

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

• Gravity affects all objects equally

The force of gravity acting on an object is also known as:

• Mass

• Weight

• Inertia

• Friction

Which force always acts perpendicular to a surface?

• Friction

• Normal force

• Tension

• Gravity

What is the net force on a 5 kg object accelerating at 2 m/s²?

• 2.5 N

• 5 N

• 10 N

• 25 N

A box is pushed across a rough surface at constant speed. What can you say about the forces?

• Friction is greater than the applied force

• The applied force equals the friction force

• The net force is not zero

• Friction is absent

Which of the following is not a type of force?

• Gravity

• Friction

• Acceleration

• Tension
