Understanding Forces and Newton's First Law

What is the net force on an object when balanced forces are acting on it?

• Depends on the object's mass

• Greater than zero

• Less than zero

• Equal to zero

When you push a car and it doesn't move, what can be inferred about the forces acting on it?

• The applied force is greater than the friction force

• The car is too heavy to move

• The applied force is less than the friction force

• The applied force and friction force are balanced

How do you calculate the net force when two forces act in opposite directions?

• Multiply the forces

• Subtract the smaller force from the larger force

• Divide the larger force by the smaller force

• Add the magnitudes of the forces

What happens to an object's velocity when unbalanced forces act on it?

• It stops moving

• It remains unchanged

• It decelerates

• It accelerates

Which of the following is an example of balanced forces in action?

• A car accelerating on a highway

• A satellite orbiting Earth at constant speed

• A ball rolling down a hill

• A person pushing a stationary wall
