What is the purpose of a force diagram?

• To measure the speed of an object

• To show all the forces acting on a receiver

• To show only the gravitational force on an object

• To calculate the mass of an object

In a force diagram, what does the dot in the middle represent?

• The speed of the object

• The receiver of the forces

• The magnitude of the force

• The direction of the force

In the example of the flamingo statue, which forces are acting on it?

• Applied force and tension

• Normal force and tension

• Gravity and friction

• Gravity and normal force

What force is responsible for the sled's movement in the example?

• Tension

• Friction

• Normal force

• Gravity

How is the magnitude of a force represented in a vector diagram?

• By the position of the arrow

• By the length of the arrow

• By the shape of the arrow

• By the color of the arrow

What unit is used to measure force?

• Joules

• Watts

• Pascals

• Newtons

When forces are in the same direction, how do you find the total force?

• Multiply them

• Add them

• Divide them

• Subtract them

What happens to an object if the net force acting on it is zero?

• It accelerates

• It slows down

• It changes direction

• It remains at rest or moves at a constant speed

Which of the following statements is true about inertia?

• Inertia is not related to mass

• Objects with less mass have more inertia
