Physics and Mathematics Quiz

What is the acceleration of a 16-gram stone when a force of 0.6 newtons is applied?

• 375 m/s²

• 0.0375 m/s²

• 37.5 m/s²

• 3.75 m/s²

If an object decelerates from 26 m/s to 24 m/s over 35 meters, what is the uniform force acting on it?

• 3 N

• -3/14 N

• -3 N

• 3/14 N

How is acceleration calculated when given initial velocity and displacement?

• a = m/F

• a = v²/2

• a = dv/dx

• a = F/m

What is the additional distance an object will travel if it decelerates at a constant rate until it stops?

• 236.6 meters

• 201.6 meters

• 35 meters

• 236 meters

What happens to an object's velocity when it stops traveling?

• Velocity halves

• Velocity remains constant

• Velocity doubles

• Velocity becomes zero

How do you find the third force acting on an object when given two other forces and acceleration?

• By subtracting the known forces from the product of mass and acceleration

• By adding the known forces

• By dividing the known forces by mass

• By multiplying the known forces by acceleration

What is the third force if two forces, 2i - 3j and 4i + 2j, act on a 2 kg object with acceleration 4i?

• 4i + 2j

• 8i

• 6i - j

• 2i + j

What is the direction of the acceleration in the vector force example?

• 5i

• 3j

• 2i

• 4i

What is the formula for force when mass and acceleration are known?

• F = m/a

• F = m + a

• F = ma

• F = a/m

What is the significance of a negative force value in the context of deceleration?

• It indicates the force is acting in the opposite direction to motion

• It means the object is speeding up

• It implies no force is acting

• It shows the force is acting in the same direction as motion
