What is a force in the context of physics?

• A state of rest

• A type of energy

• A push or a pull

• A form of matter

What happens when two equal forces act in opposite directions on an object?

• The object accelerates

• The object moves in a circle

• The object remains stationary

• The object changes shape

How does an unbalanced force affect an object's motion?

• It causes the object to change its speed or direction

• It keeps the object at rest

• It makes the object spin

• It has no effect on the object

In a frictionless environment, what happens to an object when a force is applied and then removed?

• It accelerates indefinitely

• It continues at a constant speed

• It stops immediately

• It moves in a random direction

What role does friction play in the motion of objects?

• It only affects objects in water

• It has no effect on objects

• It decelerates or stops objects

• It accelerates objects

When is a moving object considered to be under balanced forces?

• When it is accelerating

• When it is at rest

• When it is moving at a constant speed

• When it is changing direction

What is the net force on an object if 20 Newtons are applied to the right and 18 Newtons to the left?

• 38 Newtons to the right

• 2 Newtons to the right

• 2 Newtons to the left

• 38 Newtons to the left

If a plane is flying at a constant speed, what type of force is acting on it?

• No force

• Gravitational force only

• Balanced force

• Unbalanced force

How do you calculate force using mass and acceleration?

• Force = Mass - Acceleration

• Force = Mass x Acceleration

• Force = Mass / Acceleration

• Force = Mass + Acceleration

What is the net force if you push a box with 10 Newtons to the left and someone else pushes with 10 Newtons to the right?

• 10 Newtons to the left

• 10 Newtons to the right

• 20 Newtons to the left

• 0 Newtons
