Newton's Laws of Motion

Lola wants to measure her average speed when biking around her neighborhood. What information does Lola need to gather?

• Bike weight and total time traveled.

• Distance traveled and direction.

• Distance traveled and total time traveled.

• Bike weight and direction.

Newton's First Law of Motion states that an object in motion will remain in constant motion or object at rest will remain at rest, unless acted on by an outside force. Another name for this law is the

• law of acceleration

• law of gravity

• law of momentum

• law of inertia

An object will move if

• there is not amount of force or no friction acting on it.

• the amount of friction is greater than the amount of force used.

• the amount of friction and force used are the same.

• the amount of force used is greater than the amount friction.

A student is investigation accelartion and force. The student rolls five balls of different masses and records her observations in the table shown.

What claim can the student make using the data in the table?

• The acceleration of object is dependent on its mass.

• The mass of the object is directly proportional to its acceleration.

• The acceleration of object decreases ad the mass increases.

• The amount of force required to accelerate an object is proportional to its mass.

When will the nail move toward the magnet?

• When the frictional force between the nail and table is overcome by the magnetic force from the magnet.

• When the magnetic force of the nail is overcome by the frictional force between the magnet and table.

• When the gravitation force from Earth is overcome by the normal force of the table.

• When the normal force of the table is overcome by the force of gravity from Earth.

While at practice, Abbey runs down the field at 10 meters per second. She has a constant speed and does not change direction. What is Abbey's acceleration?

• 
• 
• 
• 

The student claims if she applies a force of 10 N to a block with 10 Kg, it will accelerate faster than 2 m/s. Which statement evaluates her claim correctly?

• The claim is correct because heavier objects require more force to accelerate.

• The claim is correct because heavier objects require less force accelerate.

• The claim is incorrect because heavier objects require more force to accelerate.

• The claim is correct because heavier objects require less force accelerate.

A water rocket uses an amount of water and pressurized air to send a plastic rocket several feet into the air. As the water and air rushes out the tail end of the rocket, the rocket shoots into the air.

Which statement explains the rocket's motion?

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

• The inertia of the water and air must be overcome.

• The force of gravity of the rocket is greater than the water.

• The force of gravity must be overcome to achieve lift.
