Understanding Forces and Motion

What are the two main types of forces mentioned in the passage?

• Contact forces and action-at-a-distance forces

• Gravitational forces and electrical forces

• Magnetic forces and frictional forces

• Tension forces and spring forces

Which of the following is an example of an action-at-a-distance force?

• Gravitational force

• Frictional force

• Tension force

• Normal force

What is the formula for calculating the gravitational force (weight) on Earth?

• Fgrav = m * g

• Fgrav = m / g

• Fgrav = g / m

• Fgrav = m + g

What type of friction prevents an object from moving when a force is applied?

• Static friction

• Sliding friction

• Air resistance

• Normal force

Which force is transmitted through strings, ropes, or cables when pulled tight?

• Tension force

• Spring force

• Magnetic force

• Electrical force
