Force and Motion

Front

What is the definition of force in physics?

Back

A force is a push or pull acting upon an object as a result of its interaction with another object.

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion. Unbalanced forces are not equal, causing a change in motion.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, acting parallel to the surface of contact.

Front

What are the two main types of friction?

Back

The two main types of friction are static friction (preventing motion) and kinetic friction (opposing motion).

Front

What is gravity?

Back

Gravity is the force that attracts two bodies toward each other, proportional to their masses and inversely proportional to the square of the distance between their centers.

Front

What does it mean for an object to be at rest?

Back

An object is at rest when it is not moving and the net force acting on it is zero.

Front

What is inertia?

Back

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

Front

How does mass affect the force of gravity?

Back

The greater the mass of an object, the stronger the gravitational force it exerts and experiences.

Front

What is the formula for calculating force?

Back

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