Second Law of Motion

The net force acting on an accelerating object is suddenly halved. This will cause the acceleration of the object to 

• double
• be halved
• remain unchanged

The net force acting on an accelerating object is suddenly tripled. This will cause the acceleration of the object to 

• triple
• become one-third of the original
• remain unchanged

Both the mass and the net force of an accelerating object are suddenly halved. This will cause the acceleration of the object to 

• double
• be halved
• remain unchanged

Both the mass and the net force of an accelerating object are suddenly tripled. This will cause the acceleration of the object to 

• triple
• become one-third of the original
• remain unchanged

The mass of an accelerating object becomes halved while the net force acting on it doubles. This will cause the acceleration of the object to 

• quadruple
• become one-fourth of the original
• remain unchanged

An object is accelerating at a rate of 10.0 m/s². If the net force acting upon the object is suddenly doubled, what would be the object’s new acceleration?

• 5.0 m/s²
• 15.0 m/s²
• 20.0 m/s²
• 25.0 m/s²

An object is accelerating at a rate of 10.0 m/s². If the mass of the object is suddenly doubled while retaining the same amount of net force, what would be the object’s new acceleration?

• 5.00 m/s²
• 10.0 m/s²
• 15.0 m/s²
• 20.0 m/s²

An object is accelerating at a rate of 10.0 m/s². If the mass of the object is suddenly doubled and the net force is quadrupled, what would be the object’s new acceleration?

• 5.00 m/s²
• 10.0 m/s²
• 15.0 m/s²
• 20.0 m/s²

Suppose you are inside a vehicle which is at rest. The moment the car suddenly moves forward (accelerates), you have the tendency to -

• lean forward
• lean backward
• remain steady

Suppose you are inside a vehicle moving at a constant speed. The moment the car suddenly slows down and and comes to a stop, you have the tendency to - 

• lean forward
• lean backward
• remain steady
