Force & Pressure Challenge

What type of force opposes the motion of an object sliding on a surface?

• Attraction

• Repulsion

• Gravity

• Friction

What is the SI unit of pressure?

• Pascal (Pa)

• Tesla

• Joule

• Newton

Give an example of a contact force.

• Pushing a book on a table

• Pulling a chair across the room

• Sliding a pencil on a desk

• Lifting a heavy box

Name a force that can act over a distance without direct contact.

• Nuclear force

• Electromagnetic force

• Gravitational force

• Frictional force

Define force in physics.

• Force is a constant value in physics.

• Force is a type of energy in physics.

• Force is the same as velocity in physics.

• Force in physics is any interaction that, when unopposed, will change the motion of an object.

What is the force that resists the motion of an object through a fluid?

• Lift

• Thrust

• Push

• Drag

Explain the concept of pressure in fluids.

• Pressure in fluids is the speed of the fluid.

• Pressure in fluids is the color of the fluid.

• Pressure in fluids is the temperature of the fluid.

• Pressure in fluids is the force exerted by the fluid per unit area.

How does the area of contact affect the pressure exerted by a force?

• Pressure exerted by a force decreases as the area of contact decreases.

• Pressure exerted by a force is not affected by the area of contact.

• Pressure exerted by a force increases as the area of contact remains constant.

• Pressure exerted by a force increases as the area of contact decreases.

Which force is responsible for keeping an object on a table?

• Inertia

• Gravity

• Magnetism

• Friction

What is the force that pulls objects towards the center of the Earth?

• magnetism

• repulsion

• friction

• gravity
