Forces & Motion

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s).

Front

How do you calculate speed?

Back

Speed = Distance / Time.

Front

What does Newton's first law of motion state?

Back

An object in motion will remain in motion and an object at rest will remain at rest unless acted upon by an outside force.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, causing it to slow down or stop.

Front

What is gravity?

Back

Gravity is the force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size but opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

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

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

If a ball rolls across the floor and slows down, what force is acting on it?

Back

Friction is the force that causes the ball to slow down.

Front

Calculate the speed of a student who runs 2 meters in 15 seconds.

Back

Speed = 2 meters / 15 seconds = 0.133 m/s.
