Forces and Motion Review

Front

What is equilibrium in physics?

Back

Equilibrium occurs when the net force acting on an object is zero, resulting in no change in motion.

Front

What is force?

Back

A force is a push or pull acting upon an object, measured in Newtons (N).

Front

What is the relationship between mass and force?

Back

According to Newton's second law, force equals mass times acceleration (F = ma).

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What happens to an object when balanced forces act on it?

Back

The object remains at rest or continues to move at a constant velocity.

Front

What is unbalanced force?

Back

An unbalanced force results in a change in the motion of an object, causing it to accelerate.

Front

What is gravitational force?

Back

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

Front

What is the formula for calculating weight?

Back

Weight is calculated using the formula: Weight (W) = mass (m) × gravitational acceleration (g).

Front

What is friction?

Back

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

Front

What is Newton's first law of motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an unbalanced force.
