Types of Forces (Contact)

Front

What is the force usually exerted by a surface on an object?

Back

Normal force is the force exerted by a surface perpendicular to the object resting on it.

Front

What force are you demonstrating when you pull a cup towards you?

Back

Applied Force is the force you exert when you pull or push an object.

Front

What type of contact force is described when your hand is pulled backwards as you stick it out of a moving car window?

Back

Air Resistance is the force that opposes the motion of an object through air.

Front

What is the force acting in the ropes of a swing?

Back

Tension is the force transmitted through a rope or string when it is pulled tight.

Front

How can you have less friction force?

Back

By using a smooth surface, which reduces the contact area and resistance.

Front

What is friction?

Back

Friction is a contact force that opposes the motion of an object.

Front

What is gravitational force?

Back

Gravitational force is the attraction between two masses, such as the Earth and an object.

Front

What is an example of applied force?

Back

Pushing a shopping cart is an example of applied force.

Front

What is the difference between static and kinetic friction?

Back

Static friction prevents motion between two surfaces, while kinetic friction acts on moving surfaces.

Front

What is tension in physics?

Back

Tension is the pulling force transmitted through a string, rope, or cable.
