Force

Front

What is the definition of force in physics?

Back

A force is a push or pull exerted on an object.

Front

What is the relationship between mass and force when considering motion down a hill?

Back

An object with greater mass can exert a greater force, which can affect its acceleration down a hill.

Front

What is mass?

Back

Mass is the amount of matter in an object, typically measured in kilograms.

Front

What is friction?

Back

Friction is a force that opposes the relative motion of two surfaces in contact.

Front

What happens to an object when a force is applied in the opposite direction of its motion?

Back

The object will slow down or stop due to the opposing force.

Front

How does gravity affect the motion of objects?

Back

Gravity is a force that pulls objects toward the center of the Earth, affecting their motion.

Front

What is the formula for calculating force?

Back

Force (F) is calculated using the formula F = mass (m) x acceleration (a).

Front

What is the difference between static and kinetic friction?

Back

Static friction acts on objects that are not moving, while kinetic friction acts on objects that are in motion.

Front

How does increasing the mass of an object affect the force required to move it?

Back

Increasing the mass of an object increases the force required to accelerate it, according to Newton's second law.

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 a net external force.
