What is Newton's First Law of Motion?

An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

100

What is gravity?

 The force that pulls objects toward the center of the Earth.

100

What is motion?

A change in an object's position over time.

100

What is a force?

A push or a pull.

100

What is air resistance?

The force that allows a parachute to slow a skydiver's fall.

200

What is Newton's Second Law of Motion?

his law is represented by the formula F=ma

200

What is friction?

 This force opposes motion when two surfaces rub against each other.

200

What is average speed?

 The total distance traveled divided by the total time it took.

200

What is a Newton?

 The unit used to measure force.

200

What is relative motion?

 An object is in this state when its position changes relative to another object.

300

What is Newton's Third Law of Motion?

This law states that for every action, there is an equal and opposite reaction.

300

What is net force?

The combined force of all forces acting on an object.

300

What is an object that is stopped or at rest?

 On a distance-time graph, a horizontal flat line indicates this.

300

What is weight?

The measurement of the force of gravity on an object.

300

What is static friction?

The type of friction that occurs when you rub your hands together to create heat.

400

What is the tendency of an object to resist changes in its state of motion?

What is inertia

400

What are balanced forces?

When two people pull on a rope in opposite directions with equal force, the forces are considered this.

400

What is a faster speed?

 In a distance-time graph, a steep line indicates this.

400

What is mass?

 The amount of matter in an object.

400

What is less friction?

Why a bowling ball travels farther on a smooth wood lane than on a carpeted floor, even with the same push.

500

What is 5 m/s²?

A 5 kg object is pushed with a force of 25 N. According to Newton's Second Law, what is the acceleration of the object?

500

What is 6 N to the right?

 A person is pulling a cart to the right with 10 N of force, while another person is pulling to the left with 4 N. What is the net force and direction?

500

What is 4 m/s²?

 The acceleration of a car that goes from 0 m/s to 20 m/s in 5 seconds.

500

What is gravitational force?

A force that acts between any two masses and pulls them together.

500
