Unit 4: Force Motion and Acceleration REDO

Front

What is Net Force?

Back

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

Front

What does it mean for forces to be balanced?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion of the object.

Front

What does it mean for forces to be unbalanced?

Back

Unbalanced forces are not equal and opposite, causing a change in the motion of the object.

Front

If an object is stationary, what can we say about the forces acting on it?

Back

The forces acting on it are balanced.

Front

What is Gravitational Potential Energy?

Back

Gravitational Potential Energy is the energy stored in an object due to its height above the ground, influenced by gravity.

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy of an object in motion, calculated as 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for calculating Net Force?

Back

Net Force = Force applied in one direction - Force applied in the opposite direction.

Front

What is an example of an unbalanced force?

Back

A person pushing a stationary car; if the force is strong enough, the car will start to move.

Front

What is an example of balanced forces?

Back

A book resting on a table; the force of gravity pulling it down is balanced by the normal force from the table pushing it up.

Front

What is Mechanical Advantage?

Back

Mechanical Advantage is the ratio of the output force to the input force in a machine, indicating how much a machine multiplies force.
