Can an object have a force?

A force is an interaction between objects, and forces exist in equal-and-opposite pairs. Newton’s third law: when one object exerts a force on a second object, the second object exerts an equal-and-opposite force on the first object. “equal-and-opposite” is short for “equal in magnitude but opposite in direction”.

Can an object have no force?

An object with no net forces acting on it which is initially at rest will remain at rest. If it is moving, it will continue to move in a straight line with constant velocity. Forces are “pushes” or “pulls” on the object, and forces, like velocity and acceleration are vector quantities.

Can you get force from velocity and mass?

F = m*a, where “F” is force, “m” is mass and “a” is acceleration. F = m*v, where “v” is velocity, because it can have velocity when no forces are currently applied to it.

Can an object have no momentum?

No, momentum (p) is the product of an objects mass (m) and its velocity (v). No velocity = no momentum!

Is mass a force?

Mass is the amount of matter in an object and is expressed in kilograms. It is summarized by the equation: Force (N) = mass (kg) × acceleration (m/s2). Thus, an object of constant mass accelerates in proportion to the force applied. Gravity is the variable force of attraction between any two objects.

How are velocity and force related?

Force and velocity are connected concepts — one acts on the other. Force is a measure of power. Apply force to an object, and its velocity changes. This does not work the other way around — you cannot apply velocity to an object and change its force.

Can objects move without force?

Yes, it is possible to have motion without a force being present. Newton’s first law states that, in fact, an object must continue to move at the same…

How does velocity relate to force?

Any change in an object’s velocity is called acceleration, which is the “a” in f = ma. Unless the object is moving in a vacuum, there are always forces acting on it, and all these forces added together are called the net force. The net force acts on an object to change its velocity and cause acceleration.
