Newton's 2nd Law

What is the acceleration of a 5 kg block when a force of 20 N is applied?

• 2 m/s²

• 4 m/s²

• 6 m/s²

• 8 m/s²

If two objects with different masses are pushed with the same force, which will have a greater acceleration?

• The object with the greater mass will have a greater acceleration.

• Both objects will have the same acceleration.

• The object with the lesser mass will have a greater acceleration.

• Acceleration is independent of mass.

How do you calculate acceleration using Newton's 2nd Law?

• a = F/m

• a = m/F

• a = F + m

• a = F - m

What is the effect of increasing the applied force on the acceleration of an object?

• Increasing the applied force will decrease the acceleration of the object, assuming mass remains constant.

• Increasing the applied force will have no effect on the acceleration of the object, assuming mass remains constant.

• Increasing the applied force will increase the acceleration of the object, assuming mass remains constant.

• Increasing the applied force will cause the object to stop accelerating.

What is the formula to find the net force acting on an object?

• F_net = ma

• F_net = mv^2

• F_net = m/a

• F_net = m + a

If a force of 25 N is applied to two shopping carts, one empty and one full, which will accelerate more?

• The empty shopping cart will accelerate more because it has less mass.

• The full shopping cart will accelerate more because it has more mass.

• Both shopping carts will accelerate equally because the force is the same.

• Neither shopping cart will accelerate as they are both stationary.

If an object has a mass of 10 kg and an acceleration of 2 m/s², what is the force applied?

• 10 N

• 15 N

• 20 N

• 25 N

What happens to the acceleration of an object if the mass increases while the force remains constant?

• The acceleration increases because mass is directly proportional to force.

• The acceleration remains the same regardless of mass changes.

• The acceleration decreases because acceleration is inversely proportional to mass (a = F/m).

• The acceleration becomes zero when mass increases.

Which object will accelerate more if the same force is applied: a car or a lawnmower?

• The car will accelerate more because it has more mass.

• The lawnmower will accelerate more because it has less mass.

• Both will accelerate equally because the force is the same.

• The acceleration depends on the type of surface they are on.

How do you calculate force using Newton's 2nd Law?

• F = ma, where F is the force in Newtons, m is the mass in kilograms, and a is the acceleration in meters per second squared.

• F = mv^2, where F is the force in Newtons, m is the mass in kilograms, and v is the velocity in meters per second.

• F = m/a, where F is the force in Newtons, m is the mass in kilograms, and a is the acceleration in meters per second squared.

• F = m + a, where F is the force in Newtons, m is the mass in kilograms, and a is the acceleration in meters per second squared.
