Newtons Laws & Momentum

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 with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is the formula for calculating momentum?

Back

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

Front

What is the unit of momentum?

Back

The unit of momentum is kg*m/s.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F = m*a).

Front

What is the principle of conservation of momentum?

Back

In a closed system, the total momentum before a collision is equal to the total momentum after the collision.

Front

What happens to momentum in a perfectly elastic collision?

Back

Both momentum and kinetic energy are conserved.

Front

What happens to momentum in an inelastic collision?

Back

Momentum is conserved, but kinetic energy is not conserved.

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

How does increasing landing time affect momentum?

Back

Increasing landing time reduces the force experienced by the body, allowing for a safer landing.

Front

What is the relationship between mass and velocity in momentum?

Back

Momentum increases with either an increase in mass or an increase in velocity.
