8th Grade Physics

m/s is a unit of speed that measures distance in meters traveled per second.

It indicates that the object is moving away from the start at a constant speed.

The formula for force is F = m(a), where F is force, m is mass, and a is acceleration.

Acceleration is the change in velocity over time.

A push or pull on an object is called a force.

The unit of force in SI is the Newton (N).

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

The law of inertia states that an object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity unless acted upon by a net external force.

According to Newton's second law, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

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