Which law explains why it takes more force to move a truck than to move a bike at the same speed?

Newton's 2nd Law of Motion The force acting on an object is equal to the mass of that object times its acceleration

Newton's 1st Law of Motion/ Inertia an objects resistence to change without another force acting on it.

A person in car slides to the right when going through a very sharp left turn on the highway.

1st Law/ / Inertia an object's resistence to change without another force acting on it.

2nd Law/ The force acting on an object is equal to the mass of that object times its acceleration

Which law states that if I push against a wall, the wall pushes against me?

Law 3/ For every action there is an equal and opposite action.

Law 2/ The force acting on an object is equal to the mass of that object times its acceleration

A picture is hanging on the wall, and is not moving.

1st Law/ Inertia an objects resistence to change without another force acting on it.

3rd Law/ For every action there is an equal and opposite reaction.

What kind(s) of objects have inertia?

only objects whose motion is being changed

The law of inertia (Newton’s First Law) applies

to both moving and nonmoving objects

only to objects that are not moving

A person would weigh less on on the Moon than on the Earth because . . .

Moon has less mass and therefore less gravity

Moon has more mass, and therefore more gravity

Moon has less mass, and therefore more gravity

Moon has more mass, and therefore less gravity

The strength of the force of gravity between two objects depends on _____ factors

The masses of objects and the distance between them

The masses of objects and the gravitational pull

The mass of the planet and the mass of the object

If a feather and a hammer are dropped at the same time on the moon, where there is no atmosphere, which one will hit the ground first?

Neither, there is no gravity on the moon.

hammer because it has more mass

feather because it has less mass
