Physics Quiz on Friction and Acceleration

What is the coefficient of static friction between the truck and the toolbox?

• 0.6

• 0.5

• 0.4

• 0.3

Which equation relates force to acceleration?

• F = ma

• F = mv

• F = mgh

• F = mg

Why is it important to draw a free body diagram in this problem?

• To calculate the truck's fuel efficiency

• To identify the forces acting on the toolbox

• To visualize the truck's speed

• To measure the truck's weight

What type of friction acts on the toolbox when it is not sliding?

• Kinetic friction

• Static friction

• Rolling friction

• Fluid friction

At what point does kinetic friction come into play?

• When the toolbox is at rest

• When the toolbox is sliding

• When the truck is stationary

• When the truck is accelerating

What is the formula for maximum static friction?

• f_s = μ_s * v

• f_s = μ_k * v

• f_s = μ_k * N

• f_s = μ_s * N

How is the normal force related to the weight of the toolbox?

• Normal force is greater than weight

• Normal force is less than weight

• Normal force is equal to weight

• Normal force is unrelated to weight

What happens to the mass in the equation for maximum acceleration?

• It doubles

• It increases exponentially

• It cancels out

• It becomes zero

What is the maximum acceleration of the toolbox if the static friction coefficient is 0.4?

• 5 m/s²

• 4 m/s²

• 3 m/s²

• 2 m/s²

Why does the mass of the toolbox not affect the maximum acceleration?

• Because the mass is too large

• Because the mass cancels out in the equation

• Because the mass is negligible

• Because the toolbox is weightless
