2nd 9 WK Mid Assessment CORRECTIONS

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It is measured in meters per second squared (m/s²).

Front

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken. Formula: Average Speed = Total Distance / Total Time.

Front

What does Newton's first law state?

Back

Newton's first law states that an object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity unless acted upon by a net external force.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. The greater the mass of an object, the greater its inertia.

Front

What is a chemical change?

Back

A chemical change is a process where one or more substances are transformed into different substances with different properties.

Front

What is the formula for calculating force?

Back

Force is calculated using the formula: Force = Mass x Acceleration (F = m x a).

Front

What is net force?

Back

Net force is the total force acting on an object after all the forces are combined. It determines the object's acceleration.

Front

What is the unit of force?

Back

The unit of force is the Newton (N), which is defined as the force required to accelerate a one-kilogram mass by one meter per second squared.

Front

What is the relationship between mass and acceleration?

Back

According to Newton's second law, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is the significance of distance in motion?

Back

Distance is a scalar quantity that represents the total path traveled by an object, regardless of direction.
