Front

What does Hooke's Law state?

Back

Hooke's Law states that the force (F) exerted by a spring is directly proportional to the extension (x) of the spring, expressed as F = kx, where k is the spring constant.

Front

What factors affect the strength of gravity between two objects?

Back

The strength of gravity between two objects depends on their masses and the distance between them.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

How do you calculate acceleration?

Back

Acceleration can be calculated using the formula: a = (final velocity - initial velocity) / time.

Front

What is net force?

Back

Net force is the total force acting on an object, taking into account all the individual forces acting on it.

Front

What is the formula for calculating force?

Back

The formula for calculating force is F = ma, where F is force, m is mass, and a is acceleration.

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, calculated as weight = mass × gravitational acceleration (W = mg).

Front

What is the spring constant?

Back

The spring constant (k) is a measure of a spring's stiffness, defined as the force required to extend or compress the spring by a unit distance.

Front

What is the difference between speed and velocity?

Back

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.

Front

What is inertia?

Back

Inertia is the property of an object to resist changes in its state of motion; it is directly related to the object's mass.
