Newton's Law Review Quiz

Which has more inertia: a 1-kilogram ball or a 10-kilogram ball?

10 kilogram ball

On the surface of the Earth, the force of gravity acting on one kilogram is:

9.8 Newtons

Give an example of Newton's first law acting in everyday life.

A person pushing a cart return it to itsbplace while the person is not moving

4. Give an example of the law of conservation of momentum from everyday life.

A person walking

Define the term force and list two real-life examples of a force.

A push, pull or action that has the ability to change motion. Pushing a cart or rolling a rock

The net force acting on a car rolling down a ramp is the addition of two forces. A.Name the two forces acting on the car:_ B. Which of the two forces helps the motion of the car?_ C. Which if the two forces opposes the motion of the car

A. Gravity and Friction B. Gravity C. Friction

Each force in an action-reaction pair of forces is opposite in

Direction

Any object with mass exerts a force on any other object with mass. The force is called

Gravitational force

5. In the supermarket you return a cart to the cart area. You stand still and push the cart towards the other carts. You've just learned that the cart pushes back on you too, according to Newton's Third Law. Which object is in equilibrium, you or the cart?

I am the equilibrium because i do not move

Give an example of Newton's second law acting in everyday life.

It is easier to oush a shopping cart that is empty rather than one that is full of groceries

Name a unit for measuring mass

Kg

The momentum of an object depends on what two factors?

Mass and Velocity

According to the law of universal gravitation, what two factors are important in determining the force of gravity between two objects?

Mass and distance

What is the difference between the mass of an object and the weight of an object?

Mass is a measure of the interia of an object. Weight is the force created by gravity on objects

Name a unit for measuring Force

Newton

Forces always occur in

Pairs

Name a unit for measuring weight

Pounds

Each force in an action-reaction pair of forces is equal in

Size

An object with more inertia is both harder to___________ and to _________

Start and stop

In the supermarket you return a cart to the cart area. You stand still and push the cart towards the other carts. You've just learned that the cart pushes back on you too, according to Newton's Third Law. a. Explain why the cart moves and you do not.

The cart moves and I do not because for every action there is an equal and opposite reaction.

Equilibrium. Action, Give an example of Newton's third law acting in everyday life

a cannon moves back ward as the cannon ball shoots out.
