Jupiter has about 317 times more mass than Earth. What can you infer from this fact?

That Jupiter’s gravitational force is much stronger than Earth’s gravitational force.

That Jupiter’s gravitational force is much weaker than on Earth’s gravitational force.

That Jupiter’s and Earth’s gravitational forces are equal.

Mass has no effect on the gravitational force between two objects

Magnets can be a useful tool. Look closely at the picture below which shows a magnet and various metal objects. What will happen as the magnet moves closer to the metal objects?

The magnet will attract the objects.

The magnet will become heavier.

The magnet will push the objects away

Nothing will happen to the objects

In a vacuum, what would fall faster?

They would fall at the same speed

What is Newton's third law?

Every action has an equal and opposite reaction.

If you push an object in one direction you will both move in that direction.

Look both ways before crossing the street.

Wait half an hour after eating before getting in the pool.

If the forces acting on a object are BALANCED then the object...

Is moving at a constant velocity or at rest

Is moving at a constant acceleration

President Obama is jumping up in the air. What happens at the highest point of his jump?

Gravity starts to pull him back down.

The force of his jump pulls him back down.

The force of his jump becomes greater than gravity.

Suppose an astronaut in outer space wishes to toss a ball against a very massive and perfectly elastic concrete wall and catch it as it bounces back. If the ball is as massive as the astronaut, then

the astronaut will never catch the first bounce.

the astronaut's time between catches will decrease as the game progresses

the astronaut will catch one bounce only

What is Newton's Ffrst law?

An object at rest stays at rest, an object in motion stays in motion.

Early to bed, early to rise makes a man wealthy and wise.

Objects in motion return to rest, object at rest begin motion.

Which of the following scenarios is an example of Newton's 3rd Law of Motion at work?

Two football players run toward each other and crash into one another. Both players fall backwards.

Kicking a soccer ball across a field

A car accelerates faster as it travels down a highway

The momentum change of an object is equal to the

force acting on it times its velocity

Which of the following has the largest momentum?

A pickup truck traveling down the highway

A large truck parked in a parking lot

A tightrope walker crossing Niagara Falls

The reason padded dashboards are used in cars is that they

increase the time of impact in a collision.

decrease the impulse in a collision.

increase the force of impact in a collision.

decrease the momentum of a collision

A collision is considered elastic if

there is no lasting deformation

the objects don’t stick together.

the objects that collide don't get warmer.

A cannon recoils from launching a cannonball. The speed of the cannon's recoil is small because the

cannon has far more mass than the cannonball

impulse on the cannon is less than the impulse on the cannonball.

momentum of the cannon is unchanged.

force against the cannon is relatively smal
