Forces and Motion Quiz

What is the primary difference between speed and velocity?

• Speed has direction, velocity does not
• Velocity has direction, speed does not
• Both are the same
• Speed is a vector quantity

According to Newton's Second Law, what is the relationship between force, mass, and acceleration?

• F = m/a
• F = ma
• F = m + a
• F = ma²

Which of the following best describes the relationship between displacement, velocity, and acceleration on a displacement-time graph?

• Displacement is the slope, velocity is the y-intercept, acceleration is the curvature
• Velocity is the slope, displacement is the y-intercept, acceleration is the curvature
• Acceleration is the slope, velocity is the y-intercept, displacement is the curvature
• Velocity is the slope, acceleration is the curvature, displacement is represented by the y-axis

In the equation F = ma, if the mass of an object doubles and the acceleration remains constant, what happens to the force?

• It remains the same
• It doubles
• It halves
• It quadruples

• First law
• Second law
• Third law
• Fourth law

What does the area under a velocity-time graph represent?

• Acceleration
• Speed
• Displacement
• Force

If an object's velocity is constant on a velocity-time graph, what can be inferred about its acceleration?

• The acceleration is increasing
• The acceleration is decreasing
• The acceleration is zero
• The acceleration is negative

Which of the following is a vector quantity?
