Forces Review

Front

What is kinetic friction?

Back

Kinetic friction is a contact force that opposes the motion of two surfaces sliding past each other.

Front

What is a non-contact force?

Back

A non-contact force is a push or pull force where the objects are not touching.

Front

What are contact forces?

Back

Contact forces are forces that occur when two objects are in physical contact with each other.

Front

What does a vector represent?

Back

A vector represents both the direction and magnitude of a force.

Front

What is the normal force?

Back

The normal force is the support force exerted upon an object that is in contact with a surface.

Front

What is gravity?

Back

Gravity is a non-contact force that attracts two bodies towards each other, depending on their masses.

Front

What is an example of a non-contact force?

Back

An example of a non-contact force is magnetism.

Front

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

Back

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

Front

What is the role of friction in motion?

Back

Friction opposes the motion of objects and can slow them down or stop them.

Front

What is the formula for calculating force?

Back

Force is calculated using the formula: Force = mass × acceleration (F = ma).
