P2.1 Forces And Their Effects

### Question 1

Question
What can a force do?
• Change the shape of an object
• Make an object disappear
• Change an object's state of rest or motion
• Create energy

### Question 2

Question
What is the unit of force?
• Pascal, Pa

### Question 3

Question
True or false? Every force has an equal and opposite force.
• True

### Question 4

Question
True or false? The resultant force is the product of all forces acting upon an object.
• True
• False

### Question 5

Question
Which of these situations could occur if the resultant force was zero?
• The object would remain stationary
• The object would accelerate
• The object would decelerate
• The object would move at constant speed

### Question 6

Question
Which of these situations could occur if the resultant force was not zero?
• The object would remain stationary
• The object would accelerate
• The object would decelerate
• The object would move at constant speed

### Question 8

Question
True or false? Force, mass and acceleration are linked by the equation F = ma.
• True

### Question 15

Question
What is the terminal velocity of an object?
• The speed of an object just before it lands on the ground
• The speed of an object which is guaranteed to damage it or kill it (if it is alive)
• The speed of an object at which weight and drag force are balanced

### Question 16

Question
True or false? An elastic object stays permanently deformed, even when the forces deforming it are removed.
• True
• False

### Question 17

Question
True or false? Hooke's law states that the extension of a spring is directly proportional to the force applied, providing that the limit of proportionality is not exceeded.
