UNIT 4 Newton's Laws, Forces, and Momentum

A force is described as _________ or _________ that acts on an object.

What is the velocity of a small airplane weighing 4,000 kg and with a momentum of 8,000 kg*m/s

Momentum is a vector quantity

For every action, there is an equal and opposite reaction

The symbol for momentum is

What forces are affecting the bucket?

Impulse in the formula below is symbolized by

A 5-kg object experiences a 10-N force for 10-sec, what is the momentum change?

Calculate the force of a 21 kg football player running at a rate of 3 m/s²

what is the approximate weight of an object in newtons of an object whose mass is 7kg?

The more inertia that an object has, the more mass that it has.

Force is not a vector quantity.

When the drag force of a falling object equals the force of gravity then the object has reached

In space a 100kg astronaut throws a 2kg wrench at 10m/s. What, if any, movement will she have?

Compared to your weight and mass on Earth, if you were on the moon:

An object persists at a state uniform motion in a straight line unless influenced by a force

What is the unit of momentum

When all the forces acting upon an object balance each other is called

When velocity is positive and acceleration is negative, what happens?

Force equals mass times acceleration. F=m*a

P= mass*velocity is the formula for 

What is the mass of a truck with a momentum of 20000 kg*m/s and a velocity of 40 m/s?

A change in the force of gravity on an object will affect the objects

A 5 kg block slides frictionless at 10.0 m/s for 4 secs. The magnitude of momentum is

If the mass of an object is decreased, its inertia

What causes a moving object to change direction?

The attractive force that exists between two objects that have mass.

Occurs when the forces on an object are balanced.

In a weightless environment, would it require a force to set an object in motion?

Force is a quantity that is measured using the standard metric unit known as

What is the unit for acceleration?

The force which is applied to an object by a person or another object.

Forces only exist as a result of an interaction.

the resistance an object has to a change in its state of motion.

A mass of 5kg rolls 2m in 1 sec. Which equation is used to determine momentum?

How long must an 60 N force act on a 60kg cart to raise its speed from 1 m/s to 3 m/s

Seat belts reduce the effects of momentum in automobiles

A measure of the quantity of matter is

When a dish falls, the impulse will be less if itlands on a carpet than a hard floor.

If the sum of all the forces acting on amoving object is zero, the object will

A 3000kg truck travels at 5m/s. What is its momentum?

Newton's Laws of Motion only work under Earth's gravity and are different in space.

1 Newton = 1 kg • m/s2

Force that opposes motion between two surfaces

What term is used for a "change in momentum"

What is the mass of a rock that weighs 49 newtons on Earth?

Which of the forces are a contact force?

Which object has the greatest inertia?

What is the acceleration of an object with a 42 Newton force that has a mass of a 6 kg?

Their are two types of collisions in physics
