12/6 Friday's Test

Front

What is constant speed?

Back

Constant speed means that an object is moving at the same distance over equal intervals of time.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to accelerate, change direction, or change shape. It occurs when the total forces acting on an object are not equal.

Front

How do you calculate velocity?

Back

Velocity is calculated by dividing the total distance traveled by the time taken, and it includes a direction (e.g., 75 km North in 3.5 hrs gives a velocity of 21.4 km/hr North).

Front

What is net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined. It determines the object's acceleration.

Front

What does it mean when an object is stationary?

Back

An object is stationary when it is not moving and its position does not change over time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What happens when forces are balanced?

Back

When forces are balanced, the net force is zero, and the object remains at rest or continues to move at a constant speed.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can occur due to an increase or decrease in speed or a change in direction.

Front

What is the formula for calculating force?

Back

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

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an external force.
