Forces, Motion, and Momentum

Front

What is the relationship between mass and force required to move an object?

Back

As mass increases, more force is required to move the object.

Front

What is inertia?

Back

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

Front

What type of collision occurs when objects stick together?

Back

Inelastic collision.

Front

What two forces act on a falling object?

Back

Gravity and friction.

Front

How does the surface condition affect friction?

Back

An icy road has less friction compared to a dry road.

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity.

Front

How does gravity affect falling objects?

Back

Gravity pulls objects towards the center of the Earth, accelerating them downwards.

Front

What is the formula for calculating momentum?

Back

Momentum (p) = mass (m) × velocity (v).

Front

What is the effect of friction on motion?

Back

Friction opposes the motion of objects, slowing them down.

Front

What is the difference between elastic and inelastic collisions?

Back

In elastic collisions, kinetic energy is conserved; in inelastic collisions, it is not.
