Force and Motion

Front

What is force?

Back

A push or pull on an object resulting from the object's interaction with another object.

Front

What is equilibrium in a physical system?

Back

A state where the net force acting on an object is zero, resulting in no acceleration.

Front

What is the formula for calculating net force?

Back

Net Force = Mass x Acceleration (F = ma).

Front

What is gravitational force?

Back

The force of attraction between two masses, commonly experienced as weight.

Front

What is vertical velocity?

Back

The speed of an object moving up or down in a vertical direction.

Front

What happens to the velocity of an object at its highest point when thrown vertically?

Back

The vertical velocity is zero at the highest point.

Front

What is displacement?

Back

The shortest distance from the initial to the final position of an object, including direction.

Front

How do you calculate displacement in a two-dimensional plane?

Back

Use the Pythagorean theorem: Displacement = √(x² + y²).

Front

What is the normal force?

Back

The support force exerted upon an object that is in contact with a stable surface.

Front

What is friction force?

Back

The force that opposes the relative motion of two surfaces in contact.
