Physics Test 1

__________________is how fast something moves. It measures the distance an object travels in a certain amount of time.

• speed

• distance

• time

• none of the above

Newton's 1^st law of motion is also known as the

• Law of Planetary motion

• Law of inertia

• Law of action-reaction

• Law of gravitation

Speed -

• A measure that gives rate of change and position

• A measure that dissolves to one unit

• A measure of distance an object travels per unit of time.

• A measure of distance an object travels per unit of measurement.

Speed formula

• S=S X T

• S=TX S

• S=D/T

• S=T/D

Forces are measured with units called

• Meters

• Newtons

• Length

• Miller

A force that changes an object’s motion, direction, or speed

• Balanced forces

• Force

• Unbalanced forces

• All of the above

The overall speed at which an object moves

• Average speed

• Speed

• Balanced

• Unbalanced

Velocity is speed with __________________________.

• a unicycle helmet

• direction

• fight

Acceleration is defined as the CHANGE in 

• time of motion to another place. 
• velocity 
• distance 
• speed

According to Newton's second law, if you increase the force applied to an object :

• it accelerates more
• it doesn't move
• you get more inertia
• it decelerates
