Kerr- Forces Vocabulary Flashcard

Front

What are unbalanced forces?

Back

Unbalanced forces are forces acting on an object that are not equal in size and opposite in direction, causing the object to accelerate or change its state of motion.

Front

What is friction?

Back

Friction is a force that opposes the relative motion of two surfaces in contact, acting to resist the sliding or rolling of one surface over another.

Front

Define electricity in terms of physics.

Back

Electricity is the flow of electric charge, typically carried by electrons, and is a form of energy that can be harnessed to perform work.

Front

What is a contact force?

Back

A contact force is a force that occurs when two objects are physically touching each other, such as friction, tension, and normal force.

Front

What is a force?

Back

A force is a push or pull that can cause an object to move, stop, or change direction, and is measured in newtons (N).

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion, while unbalanced forces result in a change in motion.

Front

What is the role of gravity as a force?

Back

Gravity is a force that attracts two bodies towards each other, with its strength depending on the masses of the objects and the distance between them.

Front

How does mass affect the force required to move an object?

Back

The greater the mass of an object, the more force is required to accelerate it, according to Newton's second law of motion (F=ma).

Front

What is Newton's first law of motion?

Back

Newton's first law states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by an unbalanced force.

Front

What is the formula for calculating force?

Back

The formula for calculating force is F = m * a, where F is force, m is mass, and a is acceleration.
