Physical Science 1st Term Review - 1st half

Front

What is the difference between Speed and Velocity?

Back

Speed is a measure of how fast an object is moving (scalar), while Velocity is a measure of how fast and in what direction an object is moving (vector).

Front

What is the unit of measurement for force?

Back

The unit of measurement for force is Newtons.

Front

What does Newton's 2nd Law state?

Back

Force = Mass x Acceleration.

Front

What distinguishes Velocity from Acceleration?

Back

Acceleration is a change in Velocity.

Front

In a vacuum, if a bowling ball and a feather are dropped at the same time, which hits the ground first?

Back

Both would hit at the same time.

Front

Define Scalar quantity.

Back

A scalar quantity is a physical quantity that has magnitude only, such as speed or mass.

Front

Define Vector quantity.

Back

A vector quantity is a physical quantity that has both magnitude and direction, such as velocity or force.

Front

What is the formula for calculating Force?

Back

Force = Mass x Acceleration.

Front

What is the relationship between Mass and Weight?

Back

Weight is the force exerted by gravity on an object, calculated as Weight = Mass x Gravity.

Front

What is Acceleration?

Back

Acceleration is the rate of change of velocity of an object.
