Front

What is constant velocity?

Back

Constant velocity means an object is moving at a fixed speed in a straight line without changing direction.

Front

What is constant acceleration?

Back

Constant acceleration occurs when an object's velocity changes at a consistent rate over time.

Front

What did Galileo conclude about the acceleration due to gravity?

Back

Galileo concluded that acceleration due to gravity is independent of mass.

Front

How do you calculate acceleration?

Back

Acceleration is calculated using the formula: a = (final velocity - initial velocity) / time.

Front

What is the formula for work done?

Back

Work done (W) is calculated using the formula: W = force (F) x distance (d).

Front

What is a physical property?

Back

A physical property is a characteristic of a substance that can be observed or measured without changing its identity.

Front

What is a chemical property?

Back

A chemical property is a characteristic that can only be observed during a chemical reaction, indicating how a substance interacts with other substances.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's second law, force equals mass times acceleration (F = m * a).

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is the unit of work?

Back

The unit of work is the Joule (J).
