Speed and Energy Multiple Choice Assessment

When a fast-moving car collides with a stationary (stationary means not moving) object, what happens to its energy?

• The energy stays the same
• The energy transforms into other forms like heat and sound
• The energy completely disappears
• The energy increases

Which object has more energy due to its motion?

• A bicycle moving slowly
• A bicycle moving quickly
• A parked bicycle
• All bicycles have the same energy

What happens to an object's energy when its speed decreases?

• The energy increases
• The energy stays exactly the same
• The energy decreases
• The energy multiplies

During a collision between two moving objects, what happens to their speeds?

• Both objects speed up
• Both objects maintain the same speed
• Their speeds change depending on the collision
• Both objects stop immediately

A baseball is thrown fast and hits a window. Why does the window break?

• Because the window is always weak
• Because of the baseball's high energy due to its speed
• Because windows break easily
• Because the baseball is heavy

What happens to the energy of a rolling ball as it slows down?

• It changes into other forms of energy
• It disappears completely
• It stays the same
• It increases

Which statement about speed and energy is correct?

• Speed and energy are not related
• Only heavy objects have energy when they move
• The faster an object moves, the more energy it has
• Slow objects have more energy than fast objects

What evidence shows that a moving object has energy?

• It can do work or cause changes when it hits something
• It makes a loud noise
• It is a heavy object
• It is made of metal

When two objects collide, what determines how much their speeds will change?

• Only their colors matter
• Only their sizes matter
• Their energy and mass both matter
• Only their shapes matter

What happens to the speed of two marbles after they collide?

• They always stop completely
• They always move faster
• Their speeds change based on the energy transfer
• They always keep moving at the same speed
