What is the relationship between mass and force when descending a hill?

Back

A greater mass results in a greater force due to gravity, allowing the object to descend faster.

Front

What are balanced forces?

Back

Balanced forces occur when two forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.

Front

What is the role of gravity in motion?

Back

Gravity is the force that pulls objects toward the Earth, affecting their motion and speed.

Front

How do you calculate speed?

Back

Speed is calculated using the formula S = d/t, where S is speed, d is distance, and t is time.

Front

At what point is potential energy greatest in a system?

Back

Potential energy is greatest at the highest point in a system, where the object has the most stored energy due to its position.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

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 is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion, depending on its mass.

Front

What is the formula for calculating acceleration?

Back

Acceleration is calculated using the formula a = (v_f - v_i) / t, where v_f is final velocity, v_i is initial velocity, and t is time.

Front

What is the effect of friction on motion?

Back

Friction is a force that opposes motion between two surfaces in contact, affecting the speed and direction of moving objects.
