Front

What is gravity?

Back

Gravity is a force that pulls objects toward the center of the Earth.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it is in contact with another surface.

Front

What is normal force?

Back

Normal force is the support force exerted upon an object that is in contact with another stable object.

Front

What happens to an object when the net force acting on it is zero?

Back

When the net force is zero, the object remains at rest or continues to move at a constant velocity.

Front

What is the effect of friction on a moving object?

Back

Friction slows down the object.

Front

What are opposing forces?

Back

Opposing forces are forces that act in opposite directions on an object, such as gravity and normal force.

Front

What is the role of gravity when sliding down a slide?

Back

Gravity helps to pull the person down the slide.

Front

What is an example of an applied force in sports?

Back

Kicking a soccer ball is an example of an applied force.

Front

What is the difference between contact forces and non-contact forces?

Back

Contact forces require physical contact between objects, while non-contact forces act at a distance, like gravity.
