What is the net force?

Back

The net force is the overall force acting on an object when all the individual forces are combined. It determines the object's acceleration and direction.

How does mass affect the speed of two carts when they fly apart after a spring is released?

Back

The heavier cart rolls half as fast as the lighter cart due to the conservation of momentum.

If two forces are acting in the same direction, how do you find the net force?

Back

You add the magnitudes of the forces together to find the net force.

What is a Newton?

Back

A Newton (N) is the SI unit of force, defined as the amount of force required to accelerate a one-kilogram mass by one meter per second squared.

What does Newton's 3rd Law state?

Back

For every action, there is an equal and opposite reaction.

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two masses, proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

What is friction?

Back

Friction is the force that opposes the motion of an object in contact with a surface.
