Forces

Front

What does Newton's First Law state about an object at rest?

Back

An object at rest stays at rest unless acted upon by an unbalanced force.

Front

What is acceleration classified as?

Back

Acceleration is a vector.

Front

What is the formula for calculating kinetic friction?

Back

f_k = μ_k n

Front

In a tug of war, who exerts a greater force?

Back

Neither; the forces are equal and opposite.

Front

True or False: Kinetic friction points in the opposite direction of an object's velocity.

Back

True.

Front

What is a force?

Back

A force is a push or pull acting upon an object.

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).

Front

What is the relationship between mass and acceleration in Newton's Second Law?

Back

F = ma, where F is force, m is mass, and a is acceleration.

Front

What is static friction?

Back

Static friction is the force that keeps an object at rest and prevents it from moving.

Front

What is the difference between kinetic and static friction?

Back

Kinetic friction acts on moving objects, while static friction acts on objects at rest.
